Im female and i actually looked it up apparently my mom doesn't know what shes talking about but i guess in some cases it is caused by anxiety.and what i meant i didn't know about this stuff is ive never been sexually active or had feelings for anyone. At least not in a sexual way for it be anything to do with sex.it happened when i was walking at random times.my backside would feel wet or cold like.but yeah i don't know if its anxiety it was said it could be.
