On Monday, My gf and I had a play date with another woman, who we met through a friend, but don't know that well. I had vaginal and anal sex with both of them, using a condom, and my gf gave and received oral, vag/rimming to/from her.
Yesterday, my gf noticed a red rash on both of her *** cheeks. Checking online medical/std sites it says everything from irritation from new jeans or new detergent to HIV. If it doesnt clear up, we'll get it checked out at by a doc, but has anyone else had this happen to them? What was the diagnosis?
