Sorry for the gross factor, but it's hot here and my ass tends to get sweaty on hot days, often to the point of soaking through my pants. This is embarrassing. I don't wear underwear, and I think that it would just make things worse, anyway, by trapping heat in that area. My balls sweat a lot, too, but the ass sweat is what is noticeable from the outside. I'm a bit overweight at the moment (trying to change that...), but I've had this issue since I was a kid and was of normal height/weight. This is not exactly a fun thing to ask the doctor about, so I haven't. Does anyone else have this issue, and if so what is the fix?
