Sex is almost irrelevant to our health and happiness. It’s intimacy that counts.
You can go through the motions of the physical act of sex, without anything significant occurring.
On the other hand, you can share an experience with someone; in which you both become completely lost in each other and the moment, and everything else fades away. It doesn’t really matter what your body parts are or aren’t doing.
Cherish the intimate moments you have with people, sexual or otherwise.
(frequent banging sex and intimacy is the dream, but life isn’t always like a box of chocolates or whatever)
