1)i never mb to the point of semen leakage, what is your progress on recovery?
1)yes it will cure it, as long as you leave masturbation and porn alone. only if you dont have another medical condition that causes ed.
2)since it can be taken as a test from the companies that sell, for a more substantial supply you will need to see a doctor.
3)No, mbing alot lowers sperm count, so does smoking pot, infections.
4)you might need to have that surgically corrected.
the cure for ed is abstaining from porn and mb, for at least a month or 2.
