I've been with my fiancé for 3 years now and I'm getting totally frustrated. He won't have sex with me and even when I finally get him to have sex (im always the one who itiates it) it seems he just wants to get it done and over with. He'll just pull me on top of him and that's the only way he wants it with me doing all the work and him laying there. I got so that I was so sick of always initating it that I waited for him and I broke down and started it after a month and a half. This has been going on for 2 years now and he'll get in mood where he wants sex, but they are only for like 2 weeks and then he's had enough and months will go by and nothing from him. I love him but how am I suppose to stay when he doesn't want to be with me intimately?

Ask him - he's in a relationship with you and presumably he knows why there's a problem.

Why is he still your fiancé if you are this unhappy?
