If one is burning and cannot marry, much like self-flagellation, it is a matter of how much pain you are willing to endure. As Genesis states that God created man paired with woman, and also that they be fruitful, multiply, and subdue the earth, is it obvious that God supports some form of sexual gratification. Any man and woman can remember Christ's Last Supper in an intimate way, maybe it's best we just leave it at that for now.
