Why doesn't sexual satisfaction prevent masturbation?

You can do it. It will take discipline, motivation, and hard work, but it will be worth it.
Try to occupy your time when your alone, get an accountability partner, and consider doing hard mode.
I would also suggest not sleeping with your girlfriend before you're married, but in the end, it's up to you.

 

Well happy you asked. You can never kill lust with lust. Sex is a its major manifestation. Fap is actually minor. No one here actually knows/acknowledges it. Whatever you feel for your girl without touching is love. If you write a few words of encouragement on some guy's thread who just failed, it's your concern for him due to love. If you understand what I mean continue the motion. Wishing you sucess.

 

Yes I have been where you are. Masturbation is probably almost never about "sex". Only addicted males say they need a release. You don't. So do you do it? That is different for everybody. Self medicating some pain or frustration that is gnawing at you, desire for a more fulfilling life, maybe your relationship is a joke (sex with a hot girl but no real connection), maybe you have control issues? Who knows. But the fact that you can't stop shows there is something coming on. When you get a craving try to become very aware of the present (ignore all thoughts that are in past or future and of course fantasy, these are all escapes from the present), try and ask yourself what is wrong with this moment right now (this is actually a meditation technique). Increase your self awareness and and ask yourself if you really need sex now (hint: we all like/want sex but nobady 'needs' it) or if there is something else missing that is drawing you pushing you into this cycle, if you really get no ideas then examine what happened immediately leading into this.

Radical honesty and awareness, really just another way of saying truth and love... are how you dismantle this addiction.... because any addiction is about lies, unconsciousness, and using yourself and others.

 

My guess would be your brain releases more dopamine looking at porn than it does with sex. Theres no reason why you could not give up the porn and masterbation when you have sex every day. If you continue on this path, it could cost you your girlfriend. Man up and kick it to the curb!
