It depends, Sex is a part of our biological programming and is nessesarry for the future of our species as well as followers of God. A population of people is required to worship such a being, so it would be counterintuitive for a God to slow the propagation of his followers. However, if used in excess it leads to moral decay and decadence, so God wouldn't want that either because a society of degenerates wouldn't and couldn't follow his will as it was intended. The key is balance, and that balance is achieved through marriage, a sacred vow to be loyal to one spouse and have children. It is not out of the realm of possibility that two people could be with eachother and have sex before marriage and be happy, but many people use the excuse that they want to "see what they like beforehand" and refuse to get married, have many partners, spread diseases, and remain unhappy in the long run. I personally think that if sexuality wasn't so casually expressed nowadays and people weren't so open about it, we would have a better society. I believe God would want the same.
