I had unluckily passed the 72 hours for PEP treatment, so 5 days before I had my first sex encounter, I had sex with a girl i barely know, she stated that she only had sex with 2 guys before and each time they had sex, the guys never cum inside her mouth or vagina. this is my first time sex, we do all our sex activities unprotected such as oral, fingering, french kiss, and I penetrated her for times and I got in like 2-3 times but it's only half of my penis inserted which is not more than 10 seconds I got my penis pulled out from her. I am deeply stressed on what could happen to me, today I some kind of having that the back of my left ear been really hot/burn, is it indicating that I got infected by hiv ? sometimes i got itch over my body, feeling weak the day after i did this, Doc please help me
