11 weeks ago i went to local prostitute for having oral sex but i have used a condom.she gave me blow job for 20 to 30 seconds, later i tried to have anal sex with her.i kept my penis inside her and gave 3 or 4 strokes but did not ejaculate inside her .it was too dark so i could not check the condom properly.i am worried that condom would have got some holes due to the oral sex.i had no symptoms since then,but i have read that symptoms might not show in every individual.i also read that condoms would break catastrophically but i did not have rigorious sex ,i only had sex for like 20 seconds.what are chances that hiv would have passed through those holes,please help me i am unable to concentrate on my life
