Yes, boxerbriefs are good. There was another recent question about this so I wouldn't elaborate too much here, but low-ish rise, not too long, not too short, simple fabric in a dark color is my fave. I don't care what brand, so long as they look good and clean!
Well if you have kinda a big butt and a big johnson then & nice body then yes it would but if you have a small butt,lil johnson,nasty body not gonna be sexy. Its like a fat gurl with no ass wearing a thong
Depends on the taste of your future girlfriend. Personally I think that black boxer briefs are very sexy hahah as well depends on how it looks on you. Hahah hope that helps.
