How many cases happend of hiv by only receiving oral sex from man?

Rare if ever: Oral sex is a very inefficient way of transmitting hiv, giving or receiving. Still, it's best to be safe especially with a guy you don't now, and there are plenty of other things that can be transmitted this way -- famously gonorrhea for the recipient.The burning question for you is, "am i infected?" you've asked here & have a right to a quick check from your physician. Best wishes.
