hello, i'm a 27 year old male.
i have a girlfriend, we stayed together for 3 years. we did health checkup and we were both negetive for hiv (just 8 days ago).
in the past few days she had sex with another man without protection. and yesterday i also had unprotected intercourse with her,
today just discovered she have cheated, and when i ask her,she told me she also had two unprotected sexual encounter with the other guy within the last 5 days. the second encounter happened just 24 hrs before she have the unprotected sex with me, now i suspect the guy might have hiv because he is a heroin addict for very long time, also peoples tell has hiv and doesn't take meds.
now i'm worried, and what's worrying me is
1. if she is newly infected, can she develop enough viral load within 5 days to transmit the disesse ?
2. i had sex with her 24 hrs after her second sexual encounter with the guy. she told me he ejaculated in her and she only used towel and didn't washed.
can the virus survive in her vaginal canal for 24 hrs, so i get infected from the trace of his semen because i didn't wear condoms ?
ps. she didn't have another risky encounter other than this, also i only had sex one time since she cheated on me.
help i'm stressed to death
