Hello, I'm 19 years old and had sex about 20 hours ago with a random women whom I didn't really know. Throughout the whole process, I wore a condom. I wore a condom during oral sex and vagnial sex. I'm just worried now that maybe I've caught HIV or STD some how? Like I had a really small minor cut on the bottom of the penis when I shaved earlier on in the day... I'm really scared and feel as if I'm entering the same depression mode which I faced few months back...
