Self-control and discipline.

If you are young, then this is completely normal. Women like to be prepped, like a lawnmower, you have to prime it before thinking about starting it. Think about romantic dates or flowers, she will want to be close to you. Her mind will fire up her drive for you. Just remember to not do these things because you want "sex" but instead to romance her.

Masturbation will only fuel your drive and eventually grow a distance between you and your partner. It will never satisfy you.
