Masturbation is a grave sin according to the Bible. You are the temple of God, when one sins sexually they do so against their own body. This idea that you need to ejaculate periodically is not grounded in spiritual truth.

Yes, when you first stop doing it you will start having wet dreams again. This is a demonic attack, the flesh is being denied and it is crying out, not dissimilar to the first couple days of a fast.

Those dreams are fueled by the things you see and consume daily. Don't check out that girls ass as she walks by, don't lust over IG girls, be mindful of what you allow in. Remove your eyes if necessary, it's better to be blind in heaven than seeing in hell. Make a covenant with God that you will not look at a woman lustfully, like Job. Here's the thing, you won't be able to defeat this on your own. You need to fully lean on Christ, and you also need to fear God. Fear of God is the beginning of wisdom, and to turn from evil is understanding.

Because it is written,
Be ye holy;
for I am holy.

No lewding Milady and no lewding your flesh
