Bump from legs rubbing together

Hey ladies! Anyone ever experience a bump forming as a result of your legs/butt cheeks rubbing together & sweating? When I work out I wear leggings and if I don't pull them up all the way then my legs rub together and of course I am sweating because I am working out so it makes it even worse. I can't figure out how to avoid that? I am quite curvy, and have "thunder thighs" & a butt so I guess it's to be expected but didn't know if anyone has had this problem.
