I've been masturbating about two or three times a week, and I'm worried if this could lead to impotency. I feel like my penis isn't as big as it was when I was 18, especially when it's flaccid. I can see nerves on it and also on the back of my hands. Does this mean Im getting weaker or is it normal? Am I doing it too often? Could this increase my risk of diabetes, because my mom has it?

Diabetes occur through hereditary also but not all the cases,and masturbation does not lead to impotent
