I did not have a religious upbringing and started to masturbate when i was 14. I did not feel any guilt that i did wrong. I would feel guilt if i murdered someone or slept with some ones wife.
Later in life being around protestants i found some said it was a sin and other said it was not. Even a Christian Psychologist said it was not a sin with controlled fantasy.
From the Talmud and some Jewish sources they say it is a Sin for a man to masturbate but not for a woman. because a woman does not produce seed. Because a man produces seed that is wasted he has murdered a person and produces demons.
When i was a taxi driver before i started work i did masturbate a bit more often. The reason for this was to keep my sex drive satisfied and had no problem keeping women at bay when they many times tried to come on to me for sex. This helped me to avoid sins i was convinced is sin to fornicate. Adultery or Prostitutes because i was in no sexual mood.
As i understood Jesus. I also did avoid looking at women lustfully with the thought and intent to have sex with them. To me it seemed wrong to masturbate thoughts over women i knew, especially a married woman because when i did this i was proper convicted it was wrong. King David looked with ‘‘intent’’ and it led to the actual act of Adultery.
I was not sure if Jesus did also mean a single women because how could that be adultery ?
I did read else where about out of the heart comes evil thoughts and fornication was one of them. I Took that to mean with Intent thoughts to have actual sex with single woman.
But when i just made up some controlled fantasy about sex in general there was no guilt or conviction i was doing anything wrong. I understood Lust to be Inordinate strong excessive sexual desire> To masturbate to much often. Or a married couple having to much sex. Lust for food to much etc etc. But it is OK to satisfy the normal sexual drive for sex or normal appetite for food etc.
If i was starved of food and food was in front of me i would eat. While i was a taxi-driver if i starved of sex. I could of ended up having sex with women.
Now i am coming into the catholic faith it has come to my attention that masturbation is a SIN

…I thought all the times i have masturbated and sinned. I might as well have gone off and slept with women and sinned.

I thought i will try and stop masturbation altogether. Sex is not on my brain and i don’t think about sex. The most i have lasted is six weeks. I told somebody and they said i got a addiction. I thought addiction. That is a daily thing. That is not my problem. My problem is ‘‘Conviction’’ that masturbation is wrong. Now that i am trying to stop. I get little depressed when i fail at times by its overpowering affect of attacking my mind episodically But no inner guilt. It is others that try to make me feel guilty by saying it is wrong. I have been praying for inner Conviction in this area. I only sort of 1/2 believe it could be wrong because others say it is wrong. For the first time in my life I keep having dreams of actually having sex with women and having nocturnal emissions.
Sometimes i wake up before that right on the edge of orgasm. first i gave in to it out of annoyance. Now i am starting to ignore it.
If God does not want me to see images nudity or think about sex and actually having sex. Why is it being forced unto me in dreams ?
