Well, it is fortunate that I wasn't asking you directly and instead directing a general question to anyone who reads the thread then.
I was kind of hoping someone would be a bit more talkative about it than "comfort, NEXT." Especially considering how many fashion choices people make that aren't for comfort. Maybe someone was going to surprise me and say that they do look different externally when they wear different kinds of underwear, based on the clothes they wear. Maybe someone would talk about how they wear tight everything else so the feeling of being restricted is more comfortable for them - or maybe someone would talk about how they wear loose everything else so they feel like they need the briefs to hold things in place. Or maybe someone just likes the look of the bulge.
Jeez, I learned my lesson. Never question dudes on their underwear choice. I will bow out and you guys can go back to posting "I wear boxer briefs" and leaving the thread forever.
