Masturbation is very healthy, children and babies within the womb masturbate and touch themselves so it goes to show how natural masturbation is. Masturbation is a good form of safe sex where there is all the pleasure of orgasm without risk of unwanted babies, STD's or pressure to perform, it's a good way to relieve stress, and a good way of exploring your sexuality and sexual anatomy.
Masturbation does not cause premature ejaculation or errection problems, it has no negative effects on your health at all. The only times when masturbation would be unhealthy as if you masturbate so much you forget to live your life, or if you use something harmful to masturbate with like sand paper or a cheese grater...but I'm sure you're sensible enough not to try doing that!
