Okay so been with my husband a long time, and basically he has never been able to climax via a blowjob. Not just with me but with anybody ever...

I know I'm capable of doing it from previous partners, I've tried talking to him about what he likes but he is a very poor communicator and doesn't give me anything to go on! Probably because he's never climaxed through a BJ before so he probably doesn't know himself.

I've gone at it for over an hour and still unsuccessful. It's gotten to the point now where I'm like why should I suffer the jaw ache when he can't even tell me what he enjoys?

Advice would be helpful, I want it to become enjoyable for both of us and not a chore. Anyone else had a man who can't climax through Oral?
