I have worn speedos only since I was 15 (now 73). I still wear a size 32 and shave from the neck down. I do get looks from guys - most recently one wearing "dork" shorts with the waist band of white jockeys showing. He didn't say anything but kept looking even after he passed.
The first boxers I tried on were my dad's yoke fronts. His were solid white or light blue and were a bit big. Always thought the yoke fronts were especially sexy. I was wearing his when I put one of his rubbers on for the first time.
A Speedo is the perfect male swim brief. I have only worn a speedo since I was 15. - I'm 73 now. I feel sorry for guys wearing those gigantic dork shorts. UGH!.
Note about the haircuts. I believe it is called
"High and tight" for new military recruits and is supposed to repress...
I started body shaving in HS - swim coach suggested trying it - he was shaved and gave us a quick look - no pubics. Im 73 and still keep smooth
Razor and soap in the shower works for me.
A few years ago I met a college wrestling coach in a chat room. When he was an undergraduate he wrestled - his coach gave each guy a rubber - told them to wear under their singlet - to avoid a "problem" if too aroused! He instructs his guys to do the same to keep pre cum and cum contained.
