They are mens.
A couple of pictures that I posted on this site about 4 years ago showing the type of underwear I mean. Admittedly that are boring & not...
I find old fashioned nylon y fronts to be the most comfortable by far. They give enough stretch. Unfortunately they are very difficult to get hold...
Boring but best!!
Yes v boring but v comfortable. Wouldn't wear them if I was dressing to impress though.
As far as male underwear goes I find good old fashion nylon y-fronts are the most comfortable by far.
