Orgasms

So, girls, I have a question. Here's the story:

I've been with my man for almost a year now. I love him with all my heart. We have a great relationship & we live together. We're best friends and it's just a fantastic relationship... but when we get it on, it's very hard for me to have an orgasm with him. I can have one on my own, no problem.

Whenever we have sex, he doesn't play with me. No type of foreplay. He's very vanilla, pretty against kink & I am down to try anything. I'm always on top of him. & because of his medical condition which makes him weak and tired, it's not very often we have sex. So for me to do all the work, I'm pretty okay with. I just wanna know if there's anything I can do to help me get off. Or maybe some advice on how to talk to him about it??
