i wear boxer briefs under jeans and when i'm wearing my STP i just put it inside the briefs, angle it so i'm not getting stabbed by the plastic bit and thats it it stays in place

boxers are roomy, boxer briefs fit rather well around the thighs while leaving some air in the crotch area.

I already had a pair of boxers, but I usually use them as pajamas, not underwear.  So I finally worked up enough courage to buy a pack of briefs...omigosh, soooo comfortable and no wedgie-worries. 

I live in Boxers. I never was comfortable with girly underwear. Maybe boxers are more comfy for me because all my pants are baggy though. Tranzwear rules above all else.

I think boxers fit many people considering the comfortable space they offer and nice little fancy design they come with.
