I agree that compatibility is ageless. I've met gentlemen from 20's to 60's that were sexy. I prefer a first date somewhere we can dance. If we slow dance well together, then that's my indicator.
One thing I do is ask their wife what their style is. Most wives I've talked to don't mind telling you about what their husbands are like in bed. I know I don't mind. It gives me an indication of our compatibility before we get naked and find out too late. For example: he likes to bite and tie me up. Nope, not going there.
Good luck with your date. Have fun and don't focus so much on age.
