>also I don’t want to have to confess that
Nothing that is hidden will not be known (Luke 8:17). Good luck trying to hide your sins from Christ. Owe up to them and confess them to Him, unless you want to be bound by them at the last judgment.
>How do you guys not masturbate?
It's difficult to masturbate when you burn with love and concern for the whole creation. How could I indulge in such a thing, which only benefits myself with short-term pleasure, when countless people before myself as well as right now are either suffering for the sake of many, or else being persecuted? How many are killing their own souls by hating their neighbors and hating God? How could I sit back and jack off when I'm tasked by God with helping and healing those around myself, as well as praying for the world?
And I love God's creatures. They reveal Him and give us sacramental communion with Him. So how could I do violence to my body by masturbating, when this body carries the image of God, and furthermore became consubstantial with Christ when He became incarnate as a man?
Don't get me wrong, it happens to me to masturbate sometimes (like once every 5-6 weeks). I am not a saint. I don't mean to sound like a moralizer. But, when you fall in love with someone, you are contained by something greater than yourself, rather than your usual experience of containing, comprehending, things smaller than yourself. This changes your whole perspective and it becomes completely natural to you to dedicate yourself to this person, unconditionally. Infidelities can happen now and then, because you are a bad person, but it doesn't change that your sight is only on this person you want to live for. The same is true for those who have contemplated God - when you are immersed in His mystery, what else could you do afterward but burn with love for Him and for what He made? Infidelities can happen occasionally, but this does not change your aim.
Also, often, sexual arousal and the desire to masturbate come from lusting after the human form (either pornography, or erotic artwork). But remember and acknowledge that humans carry the image of God, and even drawings of humans (and, by extension, of human-like characters) are caricatures of the image of God. People say that TV is the devil's iconography, but I would also say that pornography is the devil's iconography. Would you masturbate to an icon of the Theotokos? Or would you think about having sex with her? If you revile this idea, how much more do you think you should revile the idea of doing such a thing regarding people who are still on this earth, who you can see right now with just a few clicks?
I hope what I said can be helpful, christanon.
