I am a 21 year old guy and have never had sex, but last year I had recieved unprotected oral sex from a girl. I did not have a orgasm, and I did not give her oral pleasurei didnt know if she had a std, but since then I have not had any symptoms or anything like that. My genitals are fine, or atleast they look ok. But as I keep hearing most people dont know that they have hiv. I just want to know should I get tested for hiv even though I have only recieved oral sex one time and have not been experimenting any symptoms, no genital itching, no unusual bumps on my genitals, nothing! Should I get tested anyway just to be safe? Or is my risk very low, and should not worry to much about it?
