Swimming, Sexuality and the Womb

Why is swimming nude such a sexual/sensual experience? The reality is that when we swim, we're surrounded by fluid, just as we are in the womb. So why is that sexually arousing? Does our pre-birth experience, include sexual arousal on some level? Why is sexuality considered such a taboo in most public arenas, if that is the state from which we are born? Is it because after we "grow up," we are afraid to admit our vulnerability? Our physical state? Our "animal instinct?" Is it just in the "religious" world that we don't admit to our sensuality/sexuality? Does the rest of the world get this, but we "Christians," pretend our sexuality doesn't exist? What is moral? What is amoral? Some friends and I questioned some of this tonight. Those in the group who live within the sexual norm for our society are the most unhappy and most unfulfilled. Those who live outside the norm, and are considered by some to be amoral, are the most fulfilled. What's up with that?
