Hey Ryan, I was wondering, I know that receiving oral sex is a low risk activity for contracting HIV, but are the risks increased if you receive oral sex from someone who just finished giving oral sex to another man? Are they greater if the other man ejacualted in her mouth, than if he didn't? Thanks for all the help. You rock.

Hey there--thanks for the encouragement.

Some questions similar to yours have been asked before, and I've given (basically, I hope) the same response. It goes like this: since HIV is only known to be sexually transmitted through vaginal and anal sex, and much less frequently to the person performing oral sex on another person, those are the activities you should pay attention to. I find that people convince themselves that their encounter was unique, but unless it was fucking or sucking (not getting sucked), you shouldn't be considering yourself at risk for infection. I always add the caveat that risk can never be absent when you are engaging in, say, group oral sex (I can't help it!), but that doesn't mean you should be concerned about infection.
