I think women have really become better looking over the years...heck I see 15 year olds or even even 14, that you just feel guilty thinking of them in a sexual way. The female gender is becoming better looking and sexual from a young age these days.
There are some really hot chicks in the range of 18 to 22 but personally I'd go for the 23-26 majority. At that age women seem to mature a little bit and also become more aware of their attractiveness. A good looking woman at the age of 23-26 with a sexual personality would be the perfect one for me...but I guess I got a few more years to get there
It's just that I find younger women really immature and girly and that's a turn off as far as I'm concerned. Sure there are exceptions and women who mature quickly, but I'd rather go for the older women that have a few more years to hit the 30s.
