Then you should go live your life in a monastery where you don't have to ever encounter actual humans who enjoy their lives and live them to the fullest, sexuality included. It's one of the most basic facets of what makes us human, and to ignore it, deny it, or cover it up is just silly. Keep it relatively clean to be polite, but there's no reason to clamp it down and never speak of it. That's even worse than talking about it because it makes it seem like it's something shameful and unhealthy. That's the road that leads to burkas, brother.
