Me and my girlfriend have been together for quite a while....we finally decided to get intimate. The problem is, I satisfy her till there is not abit of energy left in her. But then on the other hand, i am not satisfied at all and have to jack off by myself cause she is too tired. I have tried to tell her about this but feel it to be mean of me. Also she is very reluctant to try different positions and i kind of have to force her sometimes but only last for about 2 mins.

So do alot of girls act the same way?
