I know this is kind of gross, but how do you prevent skid marks? Please don't say "wipe your ass" or "bathe".
Sure, sometimes its because I'm lazy about hygiene (hey I'm a straight guy) but there are times when I wipe until I'm raw and bleeding and still end up getting skid marks. This happens especially if I'm really active and/or sweating alot.
I get them pretty often and it can get embarassing, especially if my mom or girlfriend sees them. (yes both have seen them-thank God they were both very understanding and didn't make too much fun of me.)
