A good way to find out a girls true age without asking her is through their age on the website.

A girl advertising as 25+ years old is usually well over her 30's - 40's

While a girl advertised as 18 to early 20's are actually around 25 - early 30's

Since I am in my early 30's I still prefer a younger girl between 18 to 25.

Too bad they are hard to find at brothels. Most of the younger ones do outcalls.
