Nah, only 45 through 60--and seriously, only in that range. I suspect it's my desire to create a strong bond between myself and paternal figures, as I never got to know any of the older (i.e. uncles/father upward) men in my family very well. Fix what's missing, in essence.
Older man also have the advantage of being able to read a wine menu. Seriously, I'm the only one I know my age who knows a merlot from a pinot.
Winetasting ftw!
Also, being sexually attracted to someone is fine. It's when you restrict someone to being valuable only sexually (or, really, in any other way) that you get problems. There's no real difference, to my mind, between objectifying somebody for her breasts or for her keen logic skills.
As for being something I'm not, that's not the aim. I'm recognizing that one thing I am (occasionally lustful) is at odds with another, more important thing I am (all those reasons I gave) and choosing accordingly. The great thing about being sapient is the ability to examine myself, and to choose what I want to be from among the myriad impulses that make up who I am. To deny my desire for particular kinds of relationships to the exclusion of others is a greater denial of who I am than to deny a few sexual impulses.
