boyfriend help

My boyfriend and I have been together for almost 4 years now. I love him so much but he is extremely clingy, to the point where I can't handle it. He knows this too but still can't control himself... Constantly wanting to "do stuff" or have sex. We see eachother just about everyday, and if we don't it's usually a problem....We've had discussions, he knows he has a problem but yet he still can't control his actions. I am constantly feeling sad because we are always arguing about the same things(sex and seeing eachother). I don't want to make him sound so bad because he really is a great boyfriend and he will do absolutely anything for me, I just think he loves me too much, does that make sense?
