I have had issues with sex for a long time and I was always convinced they were 100% emotional, since like others have said, stress, depression and anxiety can do a number on sex drive. That said, like you I finally brought up the issue with my gyno since I thought my discomfort was due to me when in fact it is actually a physical issue. Quite frankly, it may be a physical issue that morphed into an emotional one and not the other way around. Anyway, if your difficulty persists I would not assume it's psychological and bring it up with your doctor rather than your T. There is only so much therapy can accomplish in a situation like this.
