In public pools I wear briefs of course, not thongs.
I wear thongs in my own pool.
I swim with the Masters.

Cant wait to see the picture of that one between athletic and lean - I want to buy one now but I can only afford a single suit. I want to make sure that I can actually swim in it at the gym! Thank you for sharing!

Speedo Selfies
 

It feels so nice wearing those well fitting Speedo bright colored swim briefs that rise up just below my belly button, keeping my male privates snug and secure with the backside fitting like a thong bikini. It took a lot for me to take some selfies wearing a tight Speedo swimsuit, before it's slowly stripped off by a lovely club matron. I did get to take a few selfies with her encouragement, as she slowly peeled that tight Speedo down and off me when I was soon baring it all with a healthy bouncing erection. It was fun taking some Speedo selfies while that snug and tickling lycra Speedo swim was still on me.

Speedo Selfies
 

It's so nice wearing those speedo style Adias extra snug water polo swimsuits, that do reveal a lot of a male's anatomy, like exposing his lower rear buns, a healthy male semi erection, well covered in those sexy Adias water polo swim briefs. They certainly feel so nice wearing them outlining my male extremities, when wet. I'm in no hurry to strip them off, as they like Speedo swimsuits make nice for taking Speedo selfies, while trying to work those tight wet speedo style water polo swimsuit in the the men's locker room shower.

Birthday Swim
 

Today we swam the mile as a birthday tradition in one of my favorite Neptune Sceptor Poly suits. The Y has a wonderful lap and competition pool and they keep the water perfect.

Pouch
 

Hi .. I love Neptune Sceptre. Great fabric and patterns. I find the pouch way too tight though. My cock is average, my balls on the larger side of average. I wish they would make a roomier pouch as an option. Your thoughts?

Does this stay on when you push off the wall(if you swim laps). Is it lined in the front? Thanks!

Yes, you can push off the wall with muscleskins brief, even with the model without the drawstring. It is tight if you follow the size guide. But you can customize it to have a drawstring if you want. The micro model is unlined but not too revealing in black.
I am waiting for a new one to swim laps in public pools, so more modest than the one you have seen. I will post some pics.
It will not have a drawstring, I find it more comfortable. But I don’t know if it will stay on while doing a real start from the block...

Thanks for that advice. I will check out their site. I would like a 1.5 inch side suit that is just a little cheeky. Almost all of the women at my pool wear cheeky one piece suits and a good percentage are thong suits. It makes laps interesting! In summer, we have an outside pool that is open and the guys who swim there sometimes do wear thong suits. I am not going to wear a thong but thought it would be fun to have a suit like the one you put up. I haven’t figured out how to post pictures yet.

Your pool
 

Why wear anything in your own pool?
