about 4 years ago i had "sex" with another male. i didnt know his HIV status. we had rough open mouth kiss for a period of 10 or 15 mins, i gave him oral sex for about 10 seconds, he gave me oral sex for about 10 seconds also, he grinded his penis on my butt for a little bit but he said he did not insert and he did not ejaculate at all. is there ANY risk for me here? what if i had bleeding gums or chapped lips? i have bleeding gums and chapped lips A LOT but not sure if i had them during that encounter. another encounter i had was with another man who said he was HIV neg, but you never know. we had rough open mouth kiss 3 times for about 20 seconds each. he was chewing gum at the time. risk for this one? im not sure but i had a very bad rash outbreak around my mouth area around this time but i dont remember specifically. i havent been able to get tested because of reasons but i have been living with BAD anxiety for almost 2 years now. please, any help. what do you think my risk was?
