Honestly it's rare the women look like the pics but it's no different than girls in High School getting Glamour Shots done...remember those right?
I don't think I've had what I would consider an ugly one yet. I prefer the 20 somethings for the looks but the performance is normally better when they are older.
If the lady is a 6 out of 10 but is good in the sack that number can go up dramatically.
Abby is a good example of that.
