I have had similar issues to the OP. Excessive masturbation is really really bad for a man. I'm not going on about for religious or moral reasons, that stuff is irrelevant. It drains you of energy, you're constantly tired and just want to sleep. Can be responsible for anxiety or depression, you have little to no interest in the opposite sex other then perhaps through porn which is used as another outlet for the masturbation habit. Death grip ( where you grip the penis too hard) means you lose sensitivity and so real sex becomes boring and not interesting.

When a man masturbates too much, he'll have massive dark circles under his eyes. That's something to do with too much affects the kidneys and I know this because when I quit those dark circles under my eyes want away. It had nothing to do with sleep because I need less sleep when I go through periods of abstainence.
