What's the correlation between masturbation and unhealthy sex habits or crime?

Just curious if anyone has any info on any research pertaining to this question. What I meant by unhealthy sex habits or crime would be such as prostitution, multiple/casual sex, pre-marital sex, unwanted pregnancy, STD, rape, molestation, etc, you get the picture. I need serious answers backed by research(es) and concrete data(s) and not "what I think" kinda answer. Thanks
