I'm 29, but I could easily get 18-19yos, maybe because I look young, idk, or maybe because my mind is very progressive and I'm usualy on the top of everything a "modern young adult" knows and can lead the way (but most of my gfs were 2 to 9years younger. Some 2-3years older). Not interested tho. Current gf is 7 years younger, I'm very content with it, a naturally intelligent young homely girl, we get along great. For a female the prime age is 20-25, for a male the prime age just begins at 25 (and the value increases as the time goes). Idk what you expect from a woman, but if she's not stupid from a get go, everything else is her fertility (young - fertile, old - not so much). They usualy doesn't get very much more intelligent as the time goes by (kids, family, etc..), their purpose is different, so don't have your hopes too high that if you'll chose a 30yo, she'll be A LOT more intelligent than a 21yo, lol.. so many times that was false (and the younger ones were actually a lot smarter). Haven't lied about my age yet, hasn't been a need.
