Maimonides says, "A man's wife is permitted to him and therefore, whatever he and his wife wish to pursue sexually, they may do. They may have intercourse whenever it pleases them and he may kiss any organ he wishes, and he may have intercourse in a natural and unnatural manner.
“Notice the afterglow, and embrace it. Replay in your mind scenes that made you feel particularly bonded, or close to your partner. And try to create more opportunities in your relationship for those times to happen.”
Afterglow is the lingering feeling of happiness, well-being and sexual satisfaction following sex. Studies show that this post-sex rush of good feelings really does linger, even up to 48 hours.
Adam was surrounded by other forms of life yet he still felt alone. It was only Eve’s existence and the power of their intimacy that put him at ease, certain that he had found the other half to make him whole.
The first time that intercourse is alluded to in the Bible is when “Adam knew his wife Eve.” However, this is only following their sin of eating from the Tree of Knowledge and their expulsion from the Garden of Eden- a place of supreme spiritual refinement and perfection.
To others, sex may seem out of place in the mystical, transcendent Garden of Eden between two people whose nakedness meant nothing to them. But in Judaism, sex belongs there because sex is itself spiritual, transcendent and mystical.
