I enjoy sex way more now than I did when I was younger because I'm not concerned about the way I look. It is about how much more confident I am in my skin now and how finally I'm in touch with my sensuality.
Connection with myself foremost, and of course connected with your partner. So having sex at 57 seems not disturbing at all to me it is more about how right it feels now compared to how it felt when I was younger. Less expectation and fewer inhibitions
