*shameless plug* in my thread in BDSM life, I mentioned that the age of my now-fiance was a concern to me when we started our relationship online. He is 11 years older than me and was at the time a teacher of the subject that I was studying, although at a different college in a different state. I was concerned that we wouldn't have anything in common, that he wouldn't be able to take me seriously, etc, etc.
As it turns out, it hasn't made much of a difference at all, although I like to tease him by saying things like "You know, I remember hearing this song on the playground in elementary school..." after he mentions listening to it while dancing with a girl in college.I much prefer the idea of being dominated by someone older than me than someone younger, to be honest, although I don't think it *has* to work that way.
