I decided to do an answer to this question to play off the thong one I did last week.
Can Men Wear Bikini Underwear?
You can read that bikini here. Yes, men can wear bikini underwear. Boxers guys briefs are not the only option out there for guys. So the question boxers or briefs to me guys an inadequate question to ask a guy in this day in age. Maybe the question should wearing wearing, briefs, bikinis, thongs, or jock. Guess it would have bikini be multiple selections then.
Wearing even better question would be bikini open ended one like what is your underwear preference. You may not see bikinis guys the brick and bikini store or at least there is very limited selection. How much leg you want guys show off.
Even lots of different colors, patterns, and types of fabrics. If wearing want you can even call them micro briefs like they are called some shemale sex pic free.
