There are some of us that do look older. This is Rhiannon. She won't tell me her age. But she takes good care of her skin, stays out of the sun, and moisturizes a lot. She doesn't have wrinkles but it is pretty obvious that she is in at least her mid-thirties - maybe even as old as 50. Yes, I have known real 50 year olds that look this good. (Of course they might have spent an hour on makeup alone.)
So I am guessing that when guys look for older girls, they are attracted to the ones that look their best. Not like the morning after a long night on a drinking binge. And the matchmakers know this.
