Is it normal appreciate more older women than women of my age?

As you know (go see my other story) lately I've been wandering about the friends of my mother and my aunt. Why this? Because I think older woman are more mature and stronger psychologically, and much more charming and composed bodily ..
I think it all has to do with my growth and my change of thinking, furthermore girls of my age are not grown mentally and physically in a way, I do not know ...
Well I have to tell you a secret, as I know that sometimes getting anywhere with older is very difficult, because I'm still young, and without any one see sometimes I do some moves, like putting my hand in the lap and massage, like going to cinema and put a coat over me and her so I can put my hand and massage her legs or even the V part and they always yield, some want more than that.
I want to know why so much attraction? And why some of these women have not told me anything when I'm playing that moves... Because I know that they like it and they let me do it.
