Will have to check them out for sure.

Try Bodyaware.com… they have a fair about of lingerie type thongs that are cut for a male anatomy. Not cheap but probably what you’re looking for.

I actually buy from them all the time. Also xdress which is part of their company as well. Their stuff is feminine for sure. More cross dressing style lingerie designed for men. Just ordered today from them. Some of the panty thongs I get in store look like men sporty style. Simple colors stretchy fabric.

3/4 of the thongs in my drawer (9/10 of the drawer are thongs) are from the womens side of the isle. As Blondie pointed out in the original post, it takes a little bit to find ones that will accommodate the male anatomy. Blondie is also correct the stretchy fabrics work better, most of mine are microfiber, very few are 100% cotton. My favorite brands for all day wear thongs are Jockey, Clavin Klein, and Victoria’s Secret. As I think I’ve said elsewhere on this forum, get them in some of the solid colors and if you saw me wearing one, you would be hard pressed to know they were originally made for women.

I have a few lace thongs and bikinis from Secret Male that I have purchased at erogenos.com. I prefer styles that are made for men.

I wear thong and g-string panties along with mens thongs and g-strings. Nice to have variety. Most of my panties come from Victoria's Secret or Meundies.

Recently I grabbed a thong from the drawer and went looking for my pants. When I passed the full length mirror Something looked different. My thong had a bit of lace trim at the midpoint of the front. Other than that, it seemed to be normal until I also noticed the sides seemed too brief and it became apparent I was wearing one of the wife’s VS thongs. We’re both about 34at the hip, and aside for the lack of “man room” it was a reasonable fit. But I took them off and put them in her underwear drawer. AFAIK, she hasn’t made a similar mistake, or if so neglected to share the story!

I too have crossed the aisle. I have lots of men's thongs and women's thongs. My GF and I both have lace thongs from Felina. The have enough leg elastic to keep the "goods" in. We wear the same size so I cut the labels out to tell whose is whose. They are supportive and comfortable. The thing about lace is they are really cool in the summer. As far as swimsuits go I was buying my thong suits from Koala for $34 each! They would only last a few months of lap swimming. Last spring I found women's thong bottom on Shein for $4 each. They are lined and have good front coverage and enough elastic around the legs so nothing creeps out. Going from a black Koala thong to a black Shein thong didn't raise any eyebrows. They also hold up well in the chlorine. I've just bought 15 suits for $60 on Shein which will get me through several years of lap swimming.

Many years ago before men's microfiber thongs my late wife and I were going to Europe for a 10 week vacation.   She said that rather than washing my men's cotton underwear out when we needed to do laundry why don't I buy some VS microfiber thongs and bikinis.   That was when I switched over to women's thongs.  To be honest the women's thongs actually fit better. 

Has any men tried any of these Adidas woman’s thongs? Some look like they would work for us fellas. Naturally the laser cut version will be a no go. But the wide waist versions look fine. https://www.adidas.co.uk/thongs
