I wear speedos
I'm a straight guy and I wore a speedo swim brief to the pool recently. It was obviously way more revealing than the swim trunks I'm used to but while I by no means have the body of a Greek god I thought I looked pretty good in it and wearing it at the pool was a real confidence booster. Some girls who walked by me apparently agreed and one said she thought my suit was "hot." For some weird reason speedos get a stigma of being "gay" but I think that's stupid and those that are in shape shouldn't be afraid to wear them. I think I'm going to wear a speedo more often now.
