So basically I'm a 17 year old boy and gay... I had unprotected oral sex with this guy that I was texting for a couple of weeks... I asked him if he is hiv infected and he said no.. he also claimed that he is a blood donor and that it isn't possible for me to have been infected since he is not sick with this specific illness.. I read the symptoms of hiv infection online and I read that it includes feeling tired.. i have no other symptoms and it's only been a couple of days since the incident but I just can't help but worry.. Note that it was my first time ever having any sexual activity so I think it's possible that my tiredness is caused by my anxiety over the situation.. what do you think? Thank you for your help in advance!
