Yesterday I had sex with a prostitute, but I preferred to have oral sex, but we also had vaginal for a few minutes (use condoms all the time) what I fear is that having oral sex the condom has suffered a small break that at times my penis brushed his teeth, and I have caught an STI especially AIDS, is not really what steps to take, I have 18 years I feel very bad for going to these places with friends after a party.
