You only get on your knees for two things. Let's be real.
It's easy to believe in a higher state of being when you've just blown your load. There is really no state of mind more peaceful than that post-orgasmic glow. You're one with the world, contemplative, and serene.
Sex is profound, always. Sex is the most beautiful, intimate act that two (or more, if that's your jam) people can have together. And after an intense orgasm, you become very aware of the world around you and your small, yet important place in it.
We all see heaven when we're about to climax. That moment of orgasm is about as close to God as any of us are ever going to get. I think I can speak for everyone when I say, orgasm and ascension to heaven are essentially the exact same thing.
