g spot

I've been with my husband for 4 years, and we've been married for one. When we fist started doing "stuff", as I call it, well he cared about my pleasure and getting me there and whatever but, ever since we started having sex, that's like 3 years ago, or more, he just cares about him, he doesn't try to turn me on, he just wants to get inside me and that's it and expect me to get turned on like that. I've tried to orgasm, but I can't, he tells me to touch myself but I'm not turned on enough.

Im 18 and my boyfriend and i fool around a lot. He fingers and i get orgasm but its always a cilt orgasm. He never pays attention to my g-spot. I really want to experience the different types of an orgasm. Anybody know how i can try to get him to try different things? I really don't want to have to ask him straight up. Help please!
