I prefer natural - trimmed is okay if you must, but I can't stand a bald penis/balls anymore than a bald head - just a hair fetish, I suppose. Somehow, a penis/balls without any hair at all just sits there and looks "ill/sick/bare". That's just me.
I'm the same way. Trimmed is okay but I really don't like a guy who shaves everything off...it just doesn't look right. Not to me anyway. Hair doesn't bother me like it seems to bug other people. Not sure why.
I trim things myself and that's about it. I don't have that much hair anyway.
