I am lucky if I come once every 2 weeks or so. The hormones I'm on really affect my ability to perform. Don't get me wrong, I love what they do to me, but I worry about my girlfriend/wife. She has a high libido but super understanding about it. Fortunately, we have a fuck buddy that screws both of us royally. Although I was mostly a switch/top, I absolutely love bottoming even more than I did... didn't think that was possible.
When I do masturbate I rarely finish, I get bored and distracted. The porn that does get me off is... specific.
