Even if the condom slipped, as long as the head of your penis was covered during intercourse, you had no risk for HIV. Fluids getting inside the condom aren't a risk.
The ONLY sexual risk is having unprotected anal or vaginal sex, or if the condom bursts open while having intercourse.
Condom on, no risk. Same as the answer given in 2015.
As far as I can tell, you asked this before.
"Ok so im a 35 yo male.I live in tupelo mississippi.Im married and i had a lapse in judgement.I visited a sex worker 4 days ago.We had vaginal sex for about ten minutes and were fondiling each others genitals.What concerns me is she placed a trojan magnum condom on me because its all she had.Im not that endowed,its stayed on and intact.im very guilt stricken and concerned.whats my risk?It never did slip off but was larger than i needed.i did go to completion and finished in condom."
