Can I get an "o" please?

K-la
I've been with my fiancé for 7 years now. We've had two daughter who unfortunately did not live pass their Birthdays, along with 2 miscarriages.
Since the beginning being physical has been beyond awkward. I've assumed it's because of his premature ejaculation issue but I'm starting to expect he is a sociopath. There's been times when he's done things I've asked but the next day he acts as if he'd never done or heard of it. 
Anyways what I'm getting at is, how the hell do I get this guy to touch me. I'm tired of initiating, of not having fore play, of faking it just so his ego isn't bruised. 
Because of our daughters we excepted being with one another for life. Not likely to find a partner who'd be down with your ex coming over constantly to hold infant urns. Therefore I gotta find a way to get my "o" outta him.
