Wall of text incoming. Sorry to sorta de-rail the topic here but spreading misinformation about Christianity seems to be a cool trend nowadays.
The Bible doesn't provide a good reason it basically just says not to waste your "seed" by masturbating, forgot which book or verse it was but I did read it once and it could not be clearer.
I believe you're referring to Genesis 38:9. Which many misinformed people do, because it mentions 'spilling your seed on the floor', and this always gets taken completely out of context for ??? reason, and used to misrepresent the bible.
8 Then Judah said to Er's brother Onan, "Go and sleep with your brother’s widow. Fulfill your obligation to her as her husband’s brother, so that your brother may have descendants."
9 But Onan knew that the children would not belong to him, so when he had intercourse with his brother’s widow, he let the semen spill on the ground, so that there would be no children for his brother.
10 What he did displeased the LORD, and the LORD killed him also.
Yeah, forgeted up, I get it, but in context, he's 'pulling out' to prevent his brother's wife from having a child that wouldn't belong to him. This passage says absolutely nothing about masturbating, I don't know why people keep saying it is. The bible doesn't talk about masturbating. When it says 'what he did displeased the lord', it's vague about what that means. To think it meant the SOLE ACT of the cum hitting the floor, instead of disobeying judas / being selfish / not fulfilling his obligation / the entire loving passage in context / ect., is loving stupid. There's a lot of catholic bullstuff that ended up spindoctoring this crap into 'don't masturbate', keep in mind that in older times Catholics couldn't read the bible at all and had the 'word' handed down to them by the pope, which most of the time wasn't the 'word' at all and was more in the interest of the Pope, not God. (see: crusades). Also: Christianity is generally practiced with the New Testament, when Jesus came to Earth. Genesis is the literal first book of the bible. It's a neat story, but Christians don't actually practice any of the traditions in there.
Guess it could've been a little clearer.
If you're Christian then yes, fapping is a sin.
Wrong. The problem with masturbating in the Christian faith I believe is because masturbating often involves lusting and perving over other women by extension. It's a sin in the Christian faith to look at research, masturbating or not masturbating.
