concerned much? what's my
risk of contracting the the HIV/AIDS virus  if i've
never had vaginal or anal sex, never performed oral
sex, never shared needles or had tattos, never had
blood transfusions, never had needlestick lacerations,
never shared sex toys, but received unprotected oral
sex a few times, engaged in deep french kissing, was
fingered, and i had no underwear on, and i sat on a
man's penis(which was covered by his underwear), and
his underwear was wet from his semen, and also got
some semen on my finger, wiped it off on the guy's
shirt,(i didn't look when i wiped it off on his
shirt), and then, a few seconds later, with that same
finger, touched my labia
minora, and lastly, i touched his penis(which seemed
moist), then touched a one-day-old open cut on my
lower lip? is it high risk, low risk, or no risk? 
thanks. laslty, what do you mean by theoretical risk?
is it the same as liklihood? please let me know, for
i'm very worried, and this guilt about what i did is
killin
