Hi, I had an affair with a guy and we had sex just once. I topped him, we used condom and it worked perfectly. It didn't come out or broke. But there is something that's concerning me. I gave him a blow job for about 2-4 minutes and he didn't ejaculate in my mouth. I also fingered his *** for about 3 minutes. But sometimes I bite my nails. My finger was not bleeding at all but I had a small cut because I had bite it ( but no bleeding). If he had a cut in his ***, did I put myself in risk? I'm just worried about the blow job and the fingering. Please help me. I didn't have a fever or a flu in the last 3 months. Just a bit rash on my legs. I'm desperate.
