I’ve been with my husband for five years and we just decided to start trying. The problem is for some reason he gets the feeling that he’s going to ejaculate but never does. To be honest , I don’t think he ever has. Before I was okay with that because he weren’t trying and I was on birth control, but now I don’t know if I should be worried. Should be try a specific position, lube , or should he go see a doctor? Is it me? He tells me that ejaculates most of the time when he does it himself . Help please
