I am married 2 years before. My husband does have intercourse with me and everytime he gets up when he gets sperm(fluid).

The reason he says is he don't want to have children now..

In the past 2 years of our marriage life, not even once we had complete sexual life...

Is there a chance that he has some medical problems? Can any doctors reply?

Can I medically prove myself .. in this regard and get a divorce from him?
