Welcome to our Forum. I note that you have made 18 posts in the past 6 weeks, most of which seem to deal with transmission of HIV through actions such as a trip to the barber shop, getting infected though your eyes and now as the result of taking part in a fight in which you sustained a fairly large laceration. All of this indicates that you worry a lot about HIV, perhaps more than you need to. HIV is transmitted through sex or injection of the virus deep into tissue. It is not transmitted through touching, kissing, or surface contamination with infected materials. This includes when blood splashes on people.
In the case that you describe, several comments:
1. Chances are that none of the people you were fighting with had HIV. HIV is a rare disease.
2. Your laceration sounds like it was the result of a kick or the trauma of falling off of the car, not a punch. Even if it were, this would be most unusual means of HIV transmission.
FYI, there are professional boxers who have had HIV yet there are no reports of transmission through punches/cuts/etc.
Bottom line, in my opinion, getting HIV from the fight you were in did not put you at risk for HIV. I see no reason for concern or testing related to the events you describe. On the other hand, getting yourself into situations like this in which you wind up brawling is probably not very good for your health. EWH.
Oh yeah the guys friend kicks me
