Actually, there is a medical condition for that. Can't remember
it...lemme research it up for ya.
http://en.wikipedia.org/wiki/Chronophilia
Chronophilia is a general term, you can slowly search up the
rest there.
Different men are attracted to different types of women, though
some men will sleep with any women who comes into their path.
It isn't really weird, or that rare, for there to be someone
like you who is attracted to older women, so don't worry about
it.
