Masturbation
Masturbation is fine, and is indulged in by almost all normal individuals, male and female. It's just like using the bathroom. Most every body does it, but not everybody likes to admit it. But it is a good way to relieve sexual tension besides feeling good.
There are pretty much two groups of people regarding this topic. Those that admit to masturbating, and those that lie about it.
So, go masturbate!
