This is my philosophy. Relationships are dangerious, and most times bad for everyone involved. Masturbation, on the other hand, feels good, and doesn't hurt anyone. You don't have to get involved in a relationship, nor seek out a relationship that we never have worked out in the end.
If you really want to procreate, then go to a sperm bank. Or, you could adopt, or protest abortion. But otherwise, my hand is as good as anything else.
