A boring ? A tiresome oral? Ugh. Please Help!?

First off let me say, he does know what he needs to get off. He has masturbated before and if he says he doesn't know what to do he is not being honest. He may not masturbate much but he does it or has done it. Stop and think. You should stop wasting your time on this. Sounds like he is just pulling your chain to me, get real and make him come clean (no pun intended) he knows what the problem is and is choosing not to tell you.
