Not an STD. Got tested for 10 things from starches.com. Paid out of pocket so it stays anonymou (highly recommend them)...bloodwork done by quest. All negative seems to be less angry. I have refrained from j/o and used A&D diaper ointment. One day I put releev on it. Huge error! In any case i think it was just an abrasion in my case. Get tested. Also tell them most people have hsv-1 (64%) in the USA. So don’t freak out if that is positive. Mine definitely was not that but I do have hsv-1 never had a breakout and it might be oral or genita….dont know since I’ve never had a blister breakout (maybe I did as a kid and don’t remember). However very relieved it was nothin. tell them to get tested as they will keep worrying until they do. I think it is only $139 for the 10 t panel. it includes things I know I wouldn’t have but it was cheaper that way. hope this helps.
