When I was 27 I "dated" a really cute Mexican girl that was 19, we went out for about 2 months. She was about 4'11", had long straight black hair, dark eyes, pretty face, full lips, cute little tits and a small waist with thicker hips and ass. Anyway, spending time with her was super easy and simple, I could buy her an ice cream cone at McDonald's and she was satisfied with that. Took her out to sushi, mini golf, we went for walks at the park, watched movies, etc.
It didn't last very long though because one she grew up very differently, she was from a REALLY bad part of town and came from a dysfunctional family, I actually felt bad for her. There was a big gap in regards to maturity and she came with a lot of drama at times.
I say go for it but realize that nothing of any real substance will come of this and that it should just be fun and casual. Also, a lot of guys around her age are kind of goofy so women her age who want more than that generally flock to older men.
