Well, since we (and you) have no idea if the person you got into a fight with even HAS HIV, it's all sort of a moot point to worry about this, isn't it. No one can give you an estimate on risk without knowing the status of the other person.
From your previous postings they all seem to be either sticking you with HIV tainted needles after you've passed out from drinking, getting bitten by roommates dogs and bleeding all over you or getting into boxing matches with you and bleeding all over you again.
"@Gail You can have your own opinion on things, but to say flat out something is wrong or inaccurate. Your not qualified to make such a definitive statement. Also I disagree, Semen is highly concentrated and packed with nutrients per average volume. "
Actually, as a Registered Dietitian, I'd say I'm highly qualified to make such a definitive statement, although it's doubtful you'd change your mind even if shown an accurate nutrient breakdown of semen.
