How do I arouse my boyfriend and make him not be able to resist me?

How long have you been with your boyfriend and how long have you been sexually active?

The arousal part is easier than the "not be able to resist me" part. And, yes, how old is this sexual relationship?

Not able to resist you?

Tie him down and gag him.

Of course, if he's not willing, then that's rape and it's a whole another barrel of apples.

"Unable to resist" implies that you want him to want you, regardless what HE wants.

How about just being mature enough to ASK him?
