Dude, I was reading something and found the following.

You look upon sex as an almost religious opportunity for self-dissolution and union with the universal whole. For you sex contains the seeds of enlightenment through immolation of the ego in the fires of physical passion.

It's about something else but I realized that it's somewhat of a description of tantric sex (though way too intellectualized, inadequate and confining). I'm always trying to describe this experience to people but can't seem to find the words. Tantric sex is actually an energy experience, not about the crazy positions. You won't know it until you have it and then you'll know what I'm talking about...Something happens. It's like you've disappeared and are part of the universe, yet you and your partner ARE the universe. It's one of the most amazing experiences ever. But both people have to be absolutely "connected" for that door to open (completely emotionally, psychically naked...there's more but I don't know how to formulate it into words..this is an experience I have yet to find adequate words for). It's not just emotional intimacy. It goes beyond that. You experience the connection and the beauty not only as yourself, but as your partner and as everything that exists. Suddenly, there are no boundaries ANYWHERE. You are everything and everything is you. You're not even bound by your body anymore. It's the ultimate in sexual experience but it's almost a spiritual awakening through a sexual connection. And once you've had it, something in you opens up and you change.

That experience changed the way I looked at life. And I know that people who have also experienced it regard it as almost a religious experience that changes them as well. It doesn't mean that other forms of physical intimacy aren't as good...being physical with someone comes in different flavors (tones, situations, emotional approaches, acts, whatever) and to be able to experience different ones at different times is what makes the physical side of life fun and worth having. And don't think of this experience as something that will keep you together with another person forever, for better or for worse. It's just an experience. But if you can find someone with whom you have a soul connection, and manage to each put down all of your walls and take the leap of true intimacy and connectedness for just a small window of time, you will have the chance to experience something that goes beyond words and the confines of this world.
