I think the age thing is just a number.
I think its would be better to classify it as 20 something, 30 something...
I mean I guess there are guys that would be looking for 18 year olds only, but I must say I've never really even looked at the stated age.
The profile pics and reviews tell me all I need to know.
There are a lot of older ladys that wipe the floor looks wise and confidence wise with the yonger ladys.
A good looking, sexy, confident woman is exactly that. Age is irrelivant, up to a point, but that point can certainly not be defined by a number.
