Hello,
As I realize my risk was low, I do not want to waste anyones time or ask a multitude of trivial questions, out of respect for this community.
I'll start by mentioning I have an anxiety disorder, so please bear with me.
I am 28 years old and I recently travelled to Mexico and had a number of drinks at the "club" at the resort (wasn't really a club, haha). I ended up dancing with a local girl who was staying at the resort for vacation and we ended up going to the beach to make out. By the end of the night, I ended up being mostly nude but she wasn't. I remember making out and dry humping for most of the night and then ending the night receiving a hand job. I was only naked for the hand job. Due to the sand, there was some friction which grazed my foreskin a bit, though I could tell the next morning there had been no bleeding (i.e. no clots or evidence of blood). I remember having the sense to stop her from performing oral sex on me, and I don't have any memories of having sex (I would say I remember about 95% of the details from that night). I kept on saying to her that I couldn't go any further than we had.
Furthermore, I had given her my number and we exchanged a few texts and e-mails after that night and when I asked her, she ASSURED me that we didn't have oral sex or sexual intercourse; even after asking multiple times.
I know Hepatitis C is not typically an STD, and I think I can be fairly confident we didn't have sex or oral sex. But in case my memory is not totally correct and the girl was lying (I see no reason why she would lie...she didn't deny the hand job when asked about it), do you see this as low enough risk that I should forget about it? My main concern is the very mild abrasion due to the friction from the sand.
I will get screened for the typical STDs, but is there any merit to a Hep C test? I know my status was negative before this event (low risk; no IV drugs, no blood transfusions) due to giving blood donations in the past.
