thanks very much for your thoughts lizzie, and i have learned my lesson from this experience. i was about to write back and mention this was also my first time engaging in this kind of activity, but your answer seems to have wrapped up any loose ends. i am getting tested, and once again thanks for your insight and advice. all the best.
my "take" would be that it is unlikely that you were infected.
one...the duration is almost non existent
two...it is highly unlikely that this young girl has hiv
with that being said...get tested so that you can put this behind you.
UNTIL you are in a monogamous relationship where BOTH of you have tested...ALWAYS use condoms for penetrative vaginal/anal intercourse. sex lasts a few minutes...HIV LASTS A LIFETIME.
that seems logical. 10 to 15 seconds, what would your take be? also im 99% sure she wasnt infected
common sense states that the longer someone is exposed to something...the greater the chance of becoming infected.
