So, my old (female, but not feminine) underwear is starting to get a little grungy and it's about time for me to buy a few new packs and get rid of some of the old stuff. I'm also getting a new STP device (the P Style) that's hard plastic and can apparently be manuvered through a fly in underwear instead of having to pull them down. My question is, what kind should I get? Obviously I'm used to briefs. I've worn boxers before and I'm not a big fan of them as underwear, as good as they are to sleep in. They bunch up too much for me (of course, I was wearing women's jeans with them, which may have made a difference). I was thinking of trying boxer briefs. Am I gonna have trouble with sizing because of hips, which a huge even for a woman? I wear XL men's boxer pants to bed with no trouble, but I'm not sure if it'll be the same with underwear, which is meant to fit tighter. Are they gonna fit weird when I'm not packing? Any other advice?
