i look younger than my age and i am cursed with shooing away a small legion of 20-something dingdongs (no offense to the 20-something dingdongs on this site with whom i may or may not be currently in contact. see you on PM.) lol
anyway, i'm totally joking here. but you raise an interesting point: "doomed to just date the younger" <-- what does that mean? i'm pretty sure i know what you mean, but it points to something off-center. i.e., are we missing out on something by dating non-peers? i've been joking about dating younger men [while being willing to continue dating them]. and sense there's something odd going on...maybe those of us who are willing to break convention aren't entirely comfortable with it. every time he mentions his BMX and you mention the Daily Show to a blank stare, is another nail hammered in the relationship coffin? and how bout this mentoring that happens in older/younger dynamics: hawt or not?
if we ignore the feeling of off-centeredness (which may simply be our discomfort with breaking so many societal norms, and which probably eases over the course of a long relationship): what makes someone intellectually interesting? you get to choose, not society. if you are like me and the primary sexual organ is the brain, then a spark is a spark is a spark. if you feel it, i say grab that shit by the hand and run.
