Hello.. I am very afraid.. The other night I wnet to a massage place and did not do anything sexual.. but I am woriied because I was naked and I had a scratch by my anus..( i shave down there).. I'm worried because when I was lying face down the girl was sittng on my but and kinda grinding me.. i am worried becuase it seemed like maybe she does more then "just massages" and I am worried that if she was hiv positive maybe some vaginal secretions could have dripped into the cut by my anus.. I didn't feel anything and also she was wearing panities... does this sound like I could be infected.. should I get tested just to be sure or is that a waste.... I know this sounds absurd...But I'm very afraid.. Thankyou.. I'm 19 and I'm afraid to call my parents and embarrased to ask any friends..
