Im am 17 years old and lost my virginity at the age of 16 i have never had unprotected sex until one day with my second boyfriend we only had sex for like less then a minute and he didnt cum in me but he did percum before he went inside of me but im not sure if he precame inside of me, im not sure if he had a lot of sex partners he said he didnt, and i have not had any symptoms even though i know that you may not get symptoms for years, but i am going to get tested in a few days for std and for hiv so i wanted to know what is the precentage that i might have hiv or an std even though i don't have symptoms of either.
