Are you really this stupid? I mean, your post sounds like a retarded 5 year-old wrote it. Obviously, you're an overly christianized misguided and misinformed person. I'm a physician and I can tell you that masturbation does not cause palsy, does not cause pimples, nor does it cause neurological problems. Whoever told you this is as much of a person as you appear to be.
If you are experiencing neurological problems, in your hands, you may have carpal tunnel syndrome, ms, or a variety of other neurological problems that are totally unrelated to your sexual urges and self induced ejaculations. See a doctor and have a good, thorough examination.
Don't be so stupid and naieve. Masturbation has no ill physical effects. Enjoy your penis and your body. You're 19; it's natural and healthy.
