When I temporarily left Roman Catholicism, I started masturbating because I no longer considered masturbation to be a sin. However now that I am Roman Catholic again, I am now obeying Roman Catholic doctrine that condemns masturbation.
Masturbation is a sexual act of ejaculating semen when having fantasies about someone who is not your spouse. It is basically sex without intercourse.
Mathew 5:28 says
“But I say to you, that whosoever shall look on a woman to lust after her, hath already committed adultery with her in his heart.”
Masturbation is adultry in the heart because in most cases, it involves fantasies involving people you know. When I was an apostate, I masturbated to girls from my college, young female teachers I had including ones that were married. In my heart, I had sex with them. And a question to female users here, wouldn’t you feel violated and disrespected if you found out that men masturbated to you?
So you all should stop masturbating. If you are so tempted to do so, you should handcuff your hands. You may consider not masturbating to be torture but it is not. It reduces your sexual urges so that you have better things to do than fantasize, and when you are having an erection, not masturbating lengthens the time that you are having the wonderful erection, and it also increases the amount of sexual dreams you have.
