I've expiramented to, and I have a "sweet spot". It's far from sexless. My creativity is enhanced with a flowing sex life. More resistant to stress. I connect better with others, and people think I am more charming when I have it.
I've discovered a few mindstates that aren't talked about in music or any books, that I achieve with a sexual interaction in a trusting and monogamous environment. When you don't have a lot of secrets, you can get closer. Intimacy is getting even closer.
When I don't I'm angrier, more closed off, less trusting of people, more quick to jump to negative conclusions, my entire outer energy is not as attractive. I'm more of an azzhole, so I'm quicker to piss off others or make them close off without even opening my mouth.
Besides, I believe my children seeing affection and imagining relations behind closed doors with their dad and his gf or new wife is very healthy for them to see.
