But if his GF is isn't telling him that he's not good enough, how the hell do you propose he finds out?

Maybe he didn't realize she wasn't enjoying it. I think if she doesn't think he's good at it, she should be the one to take the initiative and tell him what he could do to make it better for her. It should be something he learns from her, not from a book.

If he is THAT dumb, that he CAN NOT realize that she isn't enjoying it. Then he might want to come out of the closet and find a boyfriend.

She might've been faking enjoying it. A lot of girls do that.

well if she is faking enjoying it it is her fault. I find communication is best in a relationship. she should have told him what she likes.

Exactly, that's my point. :)

A million and one books, and any of them that are worth reading will say that she needs to let him know what she enjoys.

@Vinnie: Or you could just rely on a combination of trial & error and communication instead of depending on a book.

If his girlfriend does not inform him he is bad at oral, and she pretends to be pleasures by it, how would he know to improve his skills?

After your first dumb post you then you straight to "he must be gay", I don't know but I would be more inclined to think that you are suppressing inner desires about men than him.

Why would the mom have deja vu about a conversation about OP's size and skill in bed? Kinda weird.

that's bcoz mom may had the similar experiences with OP's dad...and hence the small penis and skills were a genetic trait from his dad...!got it...??

Skills can not be inherited. They are learned. And penis size isn't completely dependent on the father.

The fact that you have to assure everyone could mean otherwise..
