I am a 19 year old guy, and I prefer to wear boys, youth sized boxer briefs (XL size) instead of Mens sizes. I like how snug they fit and I like how they don't ride up. They aren't boxer briefs with cartoon characters on them or anything just solid colors, mostly greys and such.

As far as my preferred brand, the Hanes with the comfort band, I wear youth XL just because i'm a pretty small guy! They look better on me then stepping up to a men's small and having a saggy looking ass!
Besides that, nobody really ever sees what underwear you're wearing, and probably if they would it would not stand out cause you just wear solid colours.
its better to be snug!
