Hello everyone, I'm in panic now. Here's the thing: I'm gay, and I met another man last December. I didn't know his health. He stroked his penis first, then put the hand into my trousers and began to touch my penis. I don't know if he has body fluids or blood in his hand. I'm just worried. Then he licked my penis through his underwear. He wanted to give me a blowjob, but I refused. Then I began to masturbate him until he ejaculated. His semen ejaculated on the back of my fingers and hands. That's all. I've been living in panic for the past eight months. I'm afraid of contracting HIV. So I want to ask:
1. Am I not at risk of contracting HIV?
2. Is it possible to be infected only with injection and unprotected penetration sex, and has never been infected through in vitro contact with body fluids?
3. Is it necessary for me to test?
