Hello, I'm really scared and I need your help. I think I might have an STD or STI. About 6 months ago, I recieved oral sex from a woman, but I kept my condom on. Throughout the process, she licked my scrotom slowly one time, and I told her to stop because I was scared I might catch something. I then ejaculated into the condom, and I threw it away, but I wiped the are with isopropyl. I didn't notice anything different...other than me being paranoid. A couple days later, I got a cold, but no bumps or anything showed up. Now after 6 months, I'm got around 2 red bumps on my buttocks (they only hurt when I sit on them). Sometimes I get a slight headache, but it comes for around a couple seconds, then goes away. Now my shoulders, legs, and arms are itchy. Please help me, I'm literally crying over here.
