For me the age gap isn't such a big thing, but then that is what I've grown up with.
There are 14 years between my parents so a few years seems perfectly respectable.
A little while ago I met and started seeing a 19 year old, she definately liked older men so I was fine there and that kept the 14 year gap, although I had a bit of a problem with it and that also caused problems, (insecurity that she would want to trade me in for a younger model).
There's less gap between T and myself, she's a sprightly 23 but acts older, while I'm 35 and (like virtually every male on the planet), act younger.
In fact, I am a POTATO:
People Over Thirty Acting Twenty One.
So the age gap isn't an issue now.
