Men's beach fashion is becoming increasingly adventurous, and one of the most noticeable changes is the growing willingness of men to wear bikinis, thongs, micro briefs, and other tiny swimsuit styles.

For the flirty boy, that can be especially appealing.

A tiny bikini isn't exactly designed to make its wearer disappear into the crowd. It can communicate confidence, body positivity, playfulness, and a willingness to challenge traditional men's fashion. It can also be a surprisingly effective conversation starter.

For gay men, wearing a sexy bikini at a gay-friendly beach can make it easier to meet other men. But there's an interesting twist to the story: not every bikini-wearing guy is gay or bisexual.

Some are straight men who simply love minimal swimwear—and some discover that women are very interested in the look too.

"Flirty boy" isn't a sexual orientation.

It's more of an attitude.

A flirty boy enjoys being noticed. He likes looking good, knows when people are checking him out, and isn't necessarily afraid to respond with a smile.

At the beach, that might mean wearing something considerably more adventurous than traditional board shorts.

Instead of covering his body from waist to knee, he may choose a tiny bikini.

Or a Brazilian brief.

Or a thong.

Or a G-string.

Or one of today's micro and ultra-micro men's swimsuits.

For some guys, the swimsuit is part fashion and part social signal:

I'm comfortable being seen.

And that can make approaching someone considerably easier.

Meeting someone new at a beach can feel awkward because there isn't always an obvious reason to begin talking.

An unusual swimsuit can provide one.

"Where did you get that suit?"

"Do you always wear bikinis?"

"That's a great color on you."

"You're brave—I don't think I could wear that."

Suddenly two strangers are having a conversation.

The bikini didn't magically create attraction. What it did was make the wearer distinctive enough to provide an opening.

That's especially useful for someone who enjoys flirting.

Gay beach culture has long provided spaces where men could experiment more freely with body-conscious swimwear.

At many gay-friendly beaches, resorts, cruises, and pool parties, a tiny swim brief isn't particularly shocking.

Bikinis, thongs, and micro designs can all be part of the fashion landscape.

For a gay man who wants to meet other men, choosing sexy swimwear can therefore serve two purposes.

First, he gets to wear something he enjoys.

Second, the look can make him more approachable to people who appreciate the same aesthetic.

Someone notices the suit.

Eye contact follows.

One person smiles.

Someone says hello.

That's often how meeting people begins.

This is where stereotypes can cause confusion.

A man wearing a tiny bikini isn't necessarily gay.

Neither is a man wearing a thong.

Neither is a man wearing pink, shaving his legs, wearing jewelry, or choosing any other fashion traditionally associated with gay or feminine aesthetics.

Clothing can communicate personality and style, but it doesn't reliably communicate sexual orientation.

A straight man can love tiny bikinis.

A bisexual man can love them.

A gay man can love them.

And plenty of men from every orientation would rather wear board shorts.

The swimsuit tells you what he likes wearing—not necessarily who he wants to date.

Straight men are an interesting part of the micro-swimwear story because some have discovered that the reaction from women can be very different from what they expected.

A guy may initially worry:

What are women going to think if my swimsuit is smaller than theirs?

Some women won't like it.

Others won't care.

And some will absolutely love it.

Attraction isn't governed by a universal dress code.

A woman who finds a particular man attractive may enjoy seeing more of his body rather than less.

If he has spent months developing his legs, glutes, abs, or overall physique, covering almost everything with long board shorts isn't the only option.

A bikini puts much more of that physique on display.

This creates one of the most playful reversals in modern beach fashion.

A couple walks onto the beach.

She's wearing a bikini.

He's wearing a bikini too.

Then everyone notices that his is smaller than hers.

Maybe she's wearing a conventional bikini bottom while he's wearing a tiny Brazilian-cut men's brief.

Maybe she's wearing a relatively full bottom while he's in a thong.

Maybe both of them love micro swimwear and treat the beach like their personal fashion show.

Traditional gender rules would once have suggested that the woman should wear the revealing swimsuit while the man covers himself.

There's no particular reason modern couples need to follow that rule.

The appeal can come from several directions.

The obvious one is physical.

Minimal swimwear exposes much more of a man's legs, hips, glutes, and overall physique than board shorts do. If a woman already finds his body attractive, a well-fitting bikini isn't necessarily going to change her mind.

It may have exactly the opposite effect.

But there's another factor:

confidence.

A man willing to walk comfortably across a crowded beach in a tiny bikini is showing that he isn't excessively concerned about fitting traditional expectations.

For some women, that confidence is attractive.

For others, the appeal is fashion. They simply think a bikini looks better on a fit man than oversized shorts.

And some women enjoy the gender-role reversal itself.

It's easy to turn micro swimwear into something exclusively for muscular men, but that misses much of its appeal.

You don't need a professional-model body to wear a bikini.

People have different preferences in partners, and beaches contain bodies of every imaginable shape.

What often makes revealing swimwear work is whether the person seems comfortable wearing it.

Someone constantly pulling at his swimsuit, hiding behind his towel, and looking terrified will have a very different experience from someone who walks naturally, relaxes, swims, talks to people, and enjoys his day.

Confidence doesn't mean believing everybody finds you attractive.

It means being comfortable with the fact that you chose the swimsuit because you like it.

Revealing swimwear can sometimes function as a subtle signal of openness.

Not necessarily sexual availability.

Rather, openness to interaction.

A guy who chooses something fun, colorful, unusual, or daring may appear more approachable than someone trying to disappear into the scenery.

At an LGBTQ-friendly beach, that can help gay and bisexual men connect.

At a mainstream beach, it may attract attention from women, men, or both.

But attention shouldn't automatically be interpreted as attraction.

That's where actual flirting begins.

A swimsuit might start a conversation, but social skills determine where it goes.

Look for reciprocity.

If someone smiles back, continues talking, asks questions, or deliberately stays nearby, there may be an opportunity to keep chatting.

If someone gives short answers, turns away, puts headphones back on, or otherwise disengages, leave them alone.

That rule applies regardless of gender or orientation.

Good flirting should feel mutual.

This is particularly important when wearing unusual swimwear.

Someone may genuinely love your bikini without wanting to date you.

A gay man might compliment a straight guy's suit.

A woman might compliment a gay man's body.

Another bikini enthusiast might simply want to know where the swimsuit came from.

Accept the compliment for what it is.

If there's mutual attraction, conversation will usually provide additional clues.

This is probably the most important etiquette lesson.

You see an attractive man wearing a tiny pink bikini.

Maybe he's gay.

Maybe he's bisexual.

Maybe he's straight.

Maybe he has a girlfriend sitting ten feet away.

There's nothing wrong with saying hello or offering a respectful compliment. But the swimsuit isn't permission to make assumptions about his sexuality.

The easiest solution is wonderfully old-fashioned:

Talk to him.

For gay men specifically interested in meeting other gay men, location matters more than the swimsuit.

At a well-known LGBTQ beach, pool party, resort, or social event, there's already a greater likelihood that another man is gay or bisexual.

Sexy swimwear then becomes an additional social tool.

A distinctive bikini can make you memorable.

It can generate compliments.

It can provide an opening for conversation.

And because you're already in an LGBTQ-friendly environment, there's often less uncertainty surrounding same-sex flirting.

Still, the same rules apply: interest should be mutual and boundaries respected.

A straight man doesn't have to panic because another man compliments his bikini.

A compliment is a compliment.

In fact, wearing extremely revealing swimwear means accepting that people of different genders and orientations may notice you.

The guy wearing the suit gets to decide whom he's interested in.

That can actually make the beach more relaxed.

Instead of treating every interaction as a statement about sexuality, it becomes:

"You like my swimsuit? Thanks!"

And life moves on.

For someone accustomed to board shorts, immediately wearing an ultra-micro bikini may feel like an enormous leap.

There is no reason to do it all at once.

A guy can begin with a traditional swim brief.

Then try a higher-cut bikini.

Then a Brazilian design.

Perhaps eventually a thong.

Some men discover that each step feels dramatic for approximately ten minutes. Then they start swimming, talking, tanning, or playing volleyball and largely forget about what they're wearing.

That is often when tiny swimwear becomes genuinely enjoyable.

The best flirty-boy bikini isn't necessarily the smallest swimsuit available.

It's the one that makes you feel attractive.

Maybe that's black and understated.

Maybe it's neon pink.

Maybe it's a conventional bikini.

Maybe it's a tiny thong.

The garment should fit securely enough that you can move normally without constantly adjusting it. Public beaches also have different rules and cultural expectations, so extremely revealing designs aren't appropriate everywhere.

Choose the venue as carefully as the swimsuit.

Men's swimwear doesn't have to follow the old formula that men cover up while women show skin.

Men increasingly have access to the same spectrum of choices.

Full coverage.

Briefs.

Bikinis.

Brazilian cuts.

Thongs.

G-strings.

Micros.

Ultra-micros.

Some gay men use those styles as part of the fun and flirtation of gay beach culture. Some bisexual men enjoy the attention they receive. Some straight men simply discover that bikinis look great on their bodies—and that plenty of women agree.

That's what makes the trend interesting.

The bikini doesn't tell you whether the flirty boy wearing it is gay, straight, or bisexual.

It tells you that he's comfortable enough to wear a bikini.

If you're attracted to him, don't try to decode his entire sexuality from three square inches of spandex.

Smile.

Say hello.

Compliment the suit.

Start a conversation.

Because whether you're a gay man hoping to meet another guy or a woman who just noticed the confident straight boy whose bikini happens to be smaller than yours, sometimes a daring little swimsuit is simply a very effective way to break the ice.
