Hi.. no matter how many times people tell you, that you are most probably not infected (which i think as well) the thought will still hover in your mind,
The hard part for you is however over.. which is the wait for at least 3 months before getting tested. Go ahead and get tested, it would take only a day for you move on after that. I am telling you from experience. And therafter always have protected sex.
You can not get HIV through giving oral sex, semen or not cut or not. Saliva works well against HIV and cant last long while air is present. On the other hand other STD can be passed in this way, HIV is least of your worries. If you look through previous posts you will find plenty of HIV oral sex threads and posts and will give you an in depth look at what you need to know.
I think you do not have HIV. I had unprotected sex and had the same signs. I tested at 3 months and 6 months and all came back neg. My doc said that you can get other STD during oral sex so you have to be careful. You should alway have those boys were a non-lub condom (for oral ONLY)to protect each other from STDs.
