As for the discharge of sperm - I've found that if I masturbate two or three times in a day, and then wait about three days or so to do it again, I can increase my discharge of sperm. However, my physical doctor has prescribed a couple of new physical med's that also lower my sperm discharge. One is for my heart, and the other is for an inflamed knee. I'm not shooting out much at all when I masturbate these days. But yes, it seems like all the ap's decrease my discharge of sperm. Seeing as how I don't intend to have any babies I'm not too worried about it. Also, it is harder to get an erection, but I can force one by manipulating my ■■■■■ with my hand if I want to. As for the testoserone and dopamine, I really can't say. I am still mostly masculine in my behavior and emotions, but that could be just because of habit. As for the dopamine, I think it is about the same. I can still find pleasure in life. I can find joy in living. I'd don't know if that is because of dopamine, serotonin, or what.
