I had a brief encounter with a sex worker recently. I received oral sex with condom on and then had very brief (literally less than 10 seconds) vaginal intercourse. I stopped because I was not comfortable with the potential health of this partner: pulled out, removed condom, masturbated myself. Of course, like many others, I'm worried now. I can't imagine that there was much skin-to-skin contact, given that I aborted this encounter, but I did not actually see her vagina to notice any open sores; I did notice acne-like sores on her hips that worried me, though.
I plant to be tested for ease of mind in about 6 weeks, but is there any real worry that I can pass an infection on to others? Lets just say I did somehow contract something via skin contact -- when would I be a risk to others?
Many thanks in advance.
