Hello,
thanks for using health care magic
HIV transmission is less likely since you remember very
well that you did use a condom.
Transmission is possible if the girl is infected and if her vaginal fluid
gets into your
urethra through your penile orifice or on to a wound
on your body.
Since you were drunk, it is difficult to be certain of how it really went on
between you and the girl.
But if you are sure, the condom remained on and you are void of any wound
on your penis and did not do her oral stuff, then it is less likely that you did
pick up an infection.
However, to be certain, an HIV testing would better clarify; to be done now
and repeated three months later.
Early symptoms of infection manifests only after about 6 weeks and usually
typical of a viral infection though could go unnoticed.
Best regards and hope this helps you.
