Doctor ;. Actually i've asked my question a week ago, but i think i didn't accurately ask that time, so could i ask in detail here? about 2 weeks ago, I had 1) mutual masterbation 2) genitial frottage (for probably 1-3 mins but because i intentionalled did that for only 10-15 secs but accidental frottage could happen so i counted for 1-3 mins) 3) kissing 4) (we didn't have oral sex, but i had him suck my fingers that could have his precum and i sucked my fingers back ; 2 times and each time takes about 5 secs). All involves only precum (because he ejaculated on his belly and i am sure that i didn't let his semen contact with my genitial organs (anus, penis). Mat i ask if I could get infected of HIV, and any other STI diseases from the event i described to you. the guy i had sex with said that his last sex was 2 months ago(from the time we had sex), so it has passed for 2.5 months of his sex and he is still healthy and doesn't have any disease (if he's honest). could u please tell me the reasons beyond your answers too. moreover, i have taken PEP for 7 days and stopped because i get allergic to it. now it has passed for a week after i took PEP and i am not feeling anything strange with my body. thank you so much.
