I am very grateful for having found this practice several years ago and for working at it until it became my chosen sexual state. It's worth everything that men give up to have it.
It is hard at the beginning, but in time the intensity of sexual urges dwindle. Everything is about mindset, there is nothing hard. Your body is subject to what you experience it through. Prolonged period of not doing something your body consider it a norm. It is like when you start workout, muscles will only pain in first few days, then the body will get along with it.
That is a very difficult one. I am not married but I do ask myself how this would be possible if I was. Sometimes abstaining can grow a relationship and bring the love back if it's gone or fading. I suggest you look into Kundalini yoga
