Perhaps the issue is your neither young nor old, and although you're in prime 'MILF' territory, probably at an age that would mostly attract 18–25 year olds, who may not punt, or who you may feel uncomfortable seeing.
The good news is, like Amy said, the older you get, the more younger punters you'll attract. I started at 47 and would say it was 50:50 men younger than me, sometimes significantly, and men my own age or up to 60. In my private life I've always preferred younger men so it was great for me.
