okay so this is kinda embarrassing but my butthole won't stop itching? it's been going on for like 2 weeks now. yes, i am sexually active and i have been with the same guy for over a year and we've only ever had sex with each other and we've done anal a few times. the last time we did it was a little over a month ago? i'm not sure if that has anything to do with it but every time i go to the bathroom, it itches and is very dry. any explanation?
