does sex get better with age?

I believe it can, but there are so many factors at play. Sex for me was not a thing until my mid-20's and now after two failed relationships I've chosen to stay single for 8 years so the thing called 'sex' is like a foreign concept fading out of memory because I still don't understand how it fits into the wider subject of adult romantic/imtimate relationships.

I'm not neuro-typical so think differently to most about how intimacy and relationships work. I'm 57 now and I wouldn't know how to involve sex in any sort of relationship should it be possible to find someone who understands me.
