There is a reason a real reason why for many generations sex was put off until after marriage. I think you have discovered it. It is possible that you can communicate to him that you want more - however I would suspect you have tried that and either he is unwilling or unable (there is a difference) to comply to your requests. Ultimately you have control over your body. Cutting him off or using it to get more out of him is not actually a "bad thing" it can be a power that is abused. I would urge you to cut him off and see how he reacts. He may leave you but that is not as bad as how he is treating you already. In future, I would leave off having sex for as long as possible. I do not care how much you like the guy, or what he says - make it a ground rule - "I do not have sex for ----- months with anyone." Stick to it. 3 months is a good time - it gives you enough time to learn about the guy and if all he wants is sex he will move on before that time is up. If he wants more than just sex he will stick it out and will spend time with you beyond bed time. Not all men are nice guys many are looking for a roll in the hay and are either unwilling or unable to form a deeper relationship. Those who are willing (at least, not always able) to form a relationship will wait for it. Yes many will say "oh baby please" but you are in control of your body and the relationship when it comes to sex.

we did get to know each other and i waited 3 mouths to get in bed with him. but after we did sleep 2gether it just seemed like thats all he wanted after that.

Break up with him. Clearly he only wants you for one thing. It doesn't take a genius to figure that out and even you have figured that out yourself. Girl, have some respect for yourself and leave him while you still can. Run and don't turn back.

trust me... he wants one thing and one thing only... he's not a good boyfriend and whether you want to hear this or not, but he probably has another girlfriend that he does the same thing with. guys like this don't want to be tied down with a serious relationship. they want you when its convenient for them and could care less any other time. do yourself the favor and break up with him, ASAP! or he will continue to use you for sex and is that the kind of relationship you really want?
