I've never been attracted to celebrities. I find the "celebrity mania" quite disturbing and depressing, and hence have never really appreciated the sight of an extremely famous and middle-aged actor.
I've been attracted to the occasional male peer, however my attraction to these teenagers has never compared with my attraction to particular middle-aged men. I developed my first major crush at the age of 14. The man I desired was somewhere in his fifties, and bipolar. It was frustrating and intense. I recall constantly attempting to attract his attention, but those attempts were always failures.
Now, at 18, I am intensely attracted to a man 30+ years my senior. I'm quite sure that this is 95% because of his excellent personality, intelligence, subtle confidence and way with words.
I think that part of the reason I enjoy the idea of older men is the prospect of a challenge and chase. Older men usually don't want to "give in" to girls decades their junior, and this makes it both fun and taboo to pursue such relationships. Waha. Gosh, I sound like such an evil villain. "Come here. Come on, middle-aged man, I have some candy for you..."
