sexual frustration is a biggy for guys especially when they pussy right in front of them and cant do anything. What you need to do is make her want sex more than you. women get so turned on by guys who wait and want the girl more emotionally than sexually.
in order to control your urges, masturbating does help. most the guys i speak to say that masturbating is really bad for such ridiculous reasons such as hair loss, lose muscle mass etc. i learnt from 2 sexologists (people that actually study sex as a profession) thats masturbating is very beneficial. it increases cardiovascular health, tests the autonomic system for vasodilation and vasoconstriction of blood vessels, and it helps reduce stress anxiety and tension. but if you want to reduce the number of times you masturbate, then learn to control your emotional frame of mind by thinking about things which are not sexual. for example, look at a tree outside, analyze every part of and verbalize your thoughts in your head about it, usually helps.
also take up as many hobbies as you can, the more busy you are, the less you'll be thinking about sex. do things which require intense focus and concentration e.g. taking up a sport, art (dont draw nudes lol) etc.
i understand it is very hard to control such urges, took me a considerable amount of time to learn how to control my emotional frame of mind and to keep my head in the game.
hope that i have helped. happy gaming dude
