There is something called castration of sex offenders. Chemical castration is castration via anaphrodisiac drugs, used to reduce libido and sexual ambitions..... some argued that chemical castration is a cruel and unusual punishment. Is taking someone's weapon because of an assault or their license from drunk driving cruel and unusual punishment if they violated a law with it. If a man use his penis to commit a crime what does he need it for other than going to the restroom. Why should he be allowed to have erections to commit the next crime of a sexual nature. Why would you want him to have children of his own?

What states allow or require sex offenders to be castrated. Eight states allow chemical or surgical castration of sex offenders. They are: California, Florida, Georgia, Louisiana, Montana, Oregon, Texas, and Wisconsin.

California was the first state to allow chemical castration when its governor signed into law a measure allowing certain sex offenders to receive medroxyprogesterone acetate (MPA) treatment or its equivalent as punishment for their crime. MPA, an artificial female hormone, is commonly sold under the name Depo-Provera and is used to treat abnormal uterine bleeding, promote menstrual cycles, and treat symptoms of menopause. When used by men, MPA has the effect of reducing their testosterone levels to pre-puberty levels.

No pun intended but let's get this straight. You can lose your house, car, children and job if you violate the rules but to allow a penis violator to keep an erection is an impotent solution and not an effective action. Why should we be concerned with a penis of a man and not the psychosis of a woman from extreme stress or trauma. Voluntary" chemical or surgical castration has been in practice in many countries—reports are available from American and European countries in particular for over eighty years (chemical for circa thirty)—as an option to prison people who have broken laws of a sexual nature, castration will allow them to return to the community from otherwise lengthy prison sentencing.
