to those of you of either sex who wear thongs or strings, doesn't the back side get in direct contact with your anus?

Why not spend a few bucks on a thong and find out?

Why you all taking about your butts? I wear thongs in the summer. They're quick to slip on and pretty comfortable footwear.

Guy here, I've worn a few in my time and it's a lot like wearing a new ring on your finger, at first you notice it constantly, you feel it between your fingers and you notice when it moves, but eventually you forget it's even there. Exact same experience with thongs. After the initial sensory experience wears off its as present in your mind as the underwear you're currently wearing. It doesn't move much between the cheeks, and I can't say I've ever explicitly felt it shading my asshole.

Personally I'm not a fan of them because they don't provide the two things I wear underwear for, padding between my thighs so they don't chafe, and decency if I manage to cut it rip my pants while working. If I don't need to worry about those I'll just go commando.

I plug for a couple days at a time every once in a while, honestly you stop noticing the outside contact after a couple hours. Then you forget it's there for the most part until you move and it grinds against your prostate and you're like "oh right this is nice" and you start doing kegels and leaking in your cage

Some people aren't afraid of their assholes.

Is it true they play a G note when you fart?

Yes. It’s sexy underwear, not comfortable underwear

not with a butt plug

I think it depends on the thickness of the cheeks and thong/string. I have a thicker than average booty for a guy, and I usually just feel thongs rest between my cheeks. If I start doing some crazy stretches or yoga I'm sure it'd get a little closer to the anus as things spread out.

Strings definitely get more up close and personal, but I feel it more on the top of my ass where it meets my back and on my gooch than my anus directly. It definitely goes a little deeper between the cheeks though, but I sure don't feel it rubbing against my anus. The right thong/string should feel like almost wearing nothing.

Isn't that the whole point? But no to the latter question. Your shoes rub your toes but you probably forget about it after a while. Ever wear sandals? There's comfy pairs and uncomfy pairs.

Yes I suppose it does and no I don't notice it, it doesn't move around like you seem to be thinking. Have worn that type underwear for so long that the full back ones bother me more. Merino wool thong, believe it or not, is so ridiculously cool and comfortable.

I wear them pretty often in nightlife. I had the worst wedgie from one last night. Usually you don't notice them but mine has thick straps (it's fetishwear, I'm a performer) so yeah...

I also wear a g-string underneath for safety

I'll reiterate what most have said. They're not a reoccurring problem and you forget about them after a bit. As for direct contact with the anus, depends on how your body is shaped. If it's puckered in, then it won't. If it's flush with the curve of your inner crack, then it will. I never really paid attention to it.

I don't wear thongs, though I do have an interest in trying. That being said, I think it might be comparable to wearing flip flops; sure you'll feel it between your toes for a bit, then it stops registering.

Wash your ass, dude.

Maybe that's what they want...

"Either?"

That implies 2 and only 2 choices, we just letting this rock now? Last I heard that was transphobia.
