A comment on an earlier post made me think of this question.
In general, if you are doing it right, every time you go down on a girl she cums on your face. I mean, that's the basic goal of eating pussy, right? No one thinks it's disrespectful or gross or anything. It's just what is supposed to happen.
But try and turn the tables.
Sure there are girls out there who will let a guy cum on their face, but there are a lot of girls who find it gross, disrespectful or just plain wrong.
What, really, is the difference?
And... while we are at it, let's add the other eternal oral sex question:
Girls, do you kiss your guy after he's eaten you out?
Guys, do you kiss your girl after she's gone down on you?
Why or why not?
