so i shaved about a week ago and work in a warehouse where i sweat a lot in my butt area with a lot of friction since i walk around a lot , not sure if my skin is super irritated or if this is herpes? i had sex with a guy during the same week so im sorta freaking out if its herpes or what, we used a condom during anal, but he did go down on me. any ideas what it could be?
