I am in a relationship with a man who recently told me about something that he used to do before we met. He is flexible enough to give himself a blow job, he said, and used to do this often to get himself off. I didn’t think it was possible for men to do this, but he showed me–he can still do it! And he swallowed! Is this sort of thing normal for men to do? For straight men? How common is it? –Worried and Concerned

That your boyfriend was eager to demonstrate his superpower for you strikes me as a little odd; most straight guys who can suck themselves off are shy about demos, mostly for fear of being thought gay. (Gay guys who can suck themselves off, on the other hand, loudly brag about it over coffee at the Big Cup.) It’s possible that he brought up this thing he used to do before you met because doing it in front of his girlfriend turns him on. So I wouldn’t be surprised if he brings it up again.

Lots of guys, gay and straight, eat their own come–not “lots, a huge percentage of the male population,” but “lots, way more than your girlfriend might think.” (Until the census folks start asking about this, SCE, I won’t be able to give you any hard numbers.) Boys with freaky or religious parents sometimes eat their own come to destroy any evidence that they’ve been masturbating; young straight boys eat their own come to reassure themselves that it tastes good enough to eat, so for sure they’ll get lots of head one day; and some young gay boys eat their own come because they figure they’re going to be giving head to other guys and they might as well get used to the taste.
