There is always forgiveness with God brother.
I however struggle with the same thing, and at one time did the same thing you did. God forgived me however, and I was able to move on. however I still touch.
This situation, that I have as well, is in fact why I joined these forums today.
For the past several months I have been questioning if masturbation is a sin or not. The bible seemed to be very quiet on that matter. I can honestly say people, that when I do touch, I can do it without lust. Therefore, how can a bodily function that god has given us be sin, if there is no lust attached to it?
If God hated masturbation, then why would he even have it exist, because he is God, he could have easily removed that function from our bodies, and just make it so we can only emit sperm when having sex?
Consider this. If masturbation without lust is in fact sin, then why does it give life, and not death? One of the main things God teaches us in The Bible is that sin can produce nothing but death. I most certainly hope everyone agrees. Masturbation gives life, because science has proven that masturbation is healthy, it relieves stress and it lowers the chance of cancer, and it does other things as well.
I have come across some scripture that most certainly makes it look like God, in fact does support masturbation.
Proverbs 5:15-20 is where I come to this conclusion, what it says is worded different from version to version of the bible, but the meaning is still the same.
15 Drink water from your own cistern,
running water from your own well.
16 Should your springs overflow in the streets,
your streams of water in the public squares?
17 Let them be yours alone,
never to be shared with strangers.
18 May your fountain be blessed,
and may you rejoice in the wife of your youth.
19 A loving doe, a graceful deer—
may her breasts satisfy you always,
may you ever be captivated by her love.
20 Why be captivated, my son, by an adulteress?
Why embrace the bosom of another man's wife?
Wouldn't fountain, cistern (like a well) be referring to our sperm? Wouldn't that mean that in this scripture, God is saying that masturbation is a tool to be used to protect ourselves from the terrible sin that is Adultery? I don't know about you, but me being 17 years old, I get my sexual hormones built up so much that I need to be able to release them through masturbation ,so that I do not give into lust or adultery.
This is the conclusion I have come up with.
