Me and my boyfriend who have lived together for 4 years and we don't have sex very often. In the begining we had lots of sex. It was great then. He knew just how to please me. And make me feel good. But in the last 3 years sex has slowed a lot!!!!! Maybe we have sex 2-3 times a month....if that! I'm never in the mood. Plus he has gained some weight which I think may be playing a role in my lower sex drive as well. But I still love him and wanna have sex to make him feel good. I would rather masturbate alone as to have sex. Nothing against him but it seems that in the past year or so he hasn't been able to give me an orgasam durring sex. Also one thing that bothers me is he tries to be sensitive in bed. You know slow and soft to the touch. I need him to hold me like a man. A strong hold and just give it to me so to say. I like for my hair to be pulled and things like that. But he's not that type of guy. I don't know how to make the sex any better without saying something. But I don't want to offend him. Also i'm very shy at trying new things. I always wanna do it missionary style and am to shy to show my full naked body while having sex. So I like to stay covered. I know he's getting bored with the same ole same ole. I really need some help. I would hate to run our relationship in the ground over sex! I need help...please give me some advice.

ps.....sorry this was soooooo long
thanks
