Actually, you are morally obligated to have sex under God's command of "Go forth and multiply."
That point has been brought up previously on this topic. I don't think we are under the command from God to go forth and multiply. God told Noah and his sons to do so since everyone and everything had been erradicated from the earth due to the flood. As I've stated before, there was a neccessary need to do so and I don't see the need to do so in this day of age. If I did get married to a woman who was unable to bear children, would I be under violation of one of God's commands? I sure don't think so.
