i had an intimate encounter recently with a man i don't know well but who is sexually active with multiple partners. several times over the course of the night, there was grinding with his boxers and my (very thin mesh, skimpy/thin cut) underwear on, sometimes with my genetalia area grinding against his thigh. he fingered me over my clitoral region with underwear on, through the very porous mesh, to climax several times. he also fingered me briefly with his fingers inside my panties. i am curious what my risk is through this behavior for herpes and hpv.
