If I had a choice? Low-cut briefs. Something cute.

However, I've actually grown fond of male bikini cuts since I think they complement my frame nicely and I like how they look on me. Plus they add a certain character especially if I plan to do the the deed. I have $40 pairs of underwear. Fight me.

Boxers are just uncomfortable. They're too loose and are difficult to keep together when wearing tight pants. Plus they're decidedly unsexy. Briefs are nice when they're low-cut and have a cool style to them but bikinis are for the truly classy gentleman.
