Ok so the first few times I tried anal sex with my first anal partner after about a week I broke out in these blister like sores but they never pussed and we're just red and itchy and painful I actually went to the hospital and they ran tests and never told me what it was if I have genital herpes since they took swabs shouldn't it show up? Anyways they sent me home with a steroid it happened after that once I recal years ago and I then went to the doctors with it another swab was taken and the results showed nothing they put me on a steroid again and it cleared up. And I'm wondering wth this is because the doctors don't know! Someone with experience want to help me out with this one?
