Yes! I took up the drums when my ex left and it was the best possible therapy!
Probably the oldest age difference was a man I dated in my twenties who was 8 or 10 years older. Most men I dated then were my age or 2-3 years older. My ex was 4 years younger. Since my divorce, my first date was two years older but most were in the range of 7-10 years younger (plus a couple inappropriately younger). 5-10 years younger at my age works well - after all, I'll still likely outlive them, and with any luck we'll be sexually compatible. Men older than me are a little riskier in terms of sexual function, something that still matters to me. CMM seems randy enough though, if we get to that point I'll see how things go.
