Although many of the boy shorts I see (and the ones I have) have a big seam running up the middle of the crotch, which would not be cool for cycling. But maybe some brands are not made that way.

Another thing is to start every ride with a clean butt and clean shorts, if you're not doing that already. And change out of the shorts into clean, dry clothes as soon as possible after the ride. When I do rides that don't start at home, I bring a change of clothes and put them on as soon after the ride as possible, before driving home (or at the first gas station/fast food place I pass, if there's no restroom at the ride start).
