And one could suppose that having a reminder constantly hanging around tends to keep one's mind on it. And sex is the way the birds and bees and members of certain religions procreate, so there's actually nothing wrong with it. It produces life. It is life. Sex is delicious.
Sex is one of the pinnacles of creation.
Indeed, it is one of the reasons we, as creators of our own incarnations and dramas, separate out of the whole into individual vessels. There is a great deal of pleasure and fulfillment in the re-union from this separate state. In other words, taken to its extreme point of sublimity, sex is a spiritual experience. It transcends the physical and material. It becomes cosmic, divine, ethereal.
