I have a potential fap challenge.

You need to look for other places to channel your energy. Exercise, creative pursuits, hobbies, career goals. Find things you are passionate about and release the sexual energy you're not releasing sexually into those things.
It's called sexual transmutation.

But another thing to think about is where is your sexual frustration coming from?
I think to a degree sexual frustration only exists if you believe you need sex to feel good about yourself and function.

 

Meditation helps me a lot, specifically Zazen.

 

Is the problem here whether you should masturbate? My personal view is that the problem is fapping to porn. If you can just fap I can't see that is a problem. Most people on here don't fap Because they are rebooting their brains to stop the association of fapping and porn. If you have gone two years without either I'm sure you can fap and not worry. However if you still think you have a PMO problem I would restrain from fapping

 

This is pretty much right on point.
The key is to stop treating fapping/sex as some kind of biological need that you can't imagine going without. All that does is set you up for an eventual failure and create the illusion of 'sexual frustration' when in fact what is actually happening is that you have a whole load of extra energy from abstaining from PMO that you need to spend on activity that actually require physical and mental exertion and focus or just generally pushing yourself, whether that be studying,lifting weights,approaching women.

I think this picture links quite well to this thread
