I think it's pretty clear that masturbation doesn't do harm to anyone, and in fact is a great way to enjoy sexual pleasure, and the only way for those of us who aren't sexually active.
I'll stay out of the religious/moral whatever stuff, but for physical reasons you may not want to masturbate too much because, at least from my experience as a guy, frequent masturbation causes loss of sensitivty in one's penis, at least temporarily. When the time comes for real live sex, you may not want to masturbate too much (if at all) for, say, a day or two beforehand to ensure that you can perform when called upon.
And I do agree with Kaminski's comment that you should rely not just on external sources such as pornography for stimulation but also your own imagination, although porn can be very educational ;-) |
