Me and this guy I got to know over the phone met up and had sex we used protection but he pulled out his penis to get him hard I licked his penis and inside his pee hole and think my gums was bleeding at the time he didn’t nut in my mouth but I’m afraid of the pre cum when I licked him I licked his pee hole one piece of dry cum went into my mouth but I spit it out he told to get up and his penis was hard. After being with him a few days later I got a low grade fever, loss of appetite, tremendously weight loss,headache earache & stomach pain I got my appetite back and weight just goes up and down now I’m not worried about the condom part cause it was still on when got finished I’m worried about the oral part I’m worried he gave me a std but his friend said he no symptoms he eating fine weight fine I’m just worried about the oral part cause he was rushing me and I rushed and my teeth cause a few days before I spit into the sink and saw blood not a lot I just hope that I was not bleeding.if so I have whatever he has.
Giving oral sex is much less of a risk than unprotected vaginal or anal sex. Just licking isn't going to transmit anything - it sounds like you didn't actually put his penis into your mouth, which would be the actual risk.
I'm not sure what "dry cum" is, unless he'd already ejaculated, and had dried semen on him. If he hadn't, his fluid shouldn't be dried.
If you are having serious weight fluctuations, you need to see your doctor. That's not an STD, including HIV, if that's what you were wondering. People don't have weight issues with HIV until years and years into the infection.
There is no risk for any STD here, including HIV, but you should see your doctor about your symptoms. They could be from any number of things, but this forum is not able to address those.
