Once your kids are out of the house, learning to find yourself and what makes you happy, is much more important than seeking your next sexual partner. In fact, I believe the first step to divorce or breakup recovery is finding your own inner joy again.
Connected sex is what I'm after and what drives my fulfilling feelings. I get closeness from sex. I get relaxation and bonding from sex. And with my wiring (my Love Language is touch) sex or "skin time" is important. But skin time can be cuddling. Or hugging and kissing on the couch.
