Hey, Voss! I think I get what you are saying. I have always gravitated toward people older than I am. Right now my two best friends are five years older and ten years older than I am. I like to think in some ways I am more mature than folks my age. (Who knows?)
I like to read books on writing. In fact, I even taught English, and I do write. We have a writers' social group, although I am not sure how active it is. But I belong, and it could get going again!
We also have a transgender forum, where you are sure to meet some folks who understand that aspect of you. Here is that link:
Transgender & Other Gender Support - Forums at Psych Central.
I hope these suggestions will be a start, anyway. Believe me, we have members with all sorts of interests and "bents."
