My partner gave me oral sex without protection on me..what are the risks? also when we had sex the condom unrolled a little, much risk to this? thanks

Very low risk if...: If both partners have been wisely selective in choosing partners, and thus have no history of having multiple partners in their pasts, then there is very little additional risk to having oral sex. If there are unknown illnesses, such as syphilis or herpes, which can pass germs without obvious symptoms, one can become infected. Same is true for poop germs (parasites, Salmonella, E. coli, etc...).
