Well, put your money where you mouth is. Post a recent picture and let us guess
I pretty much always date younger. All their parts are still in the proper place, which is a plus.
I think a big reason it is more common for older men to date younger women is the child-bearing issue. A 60 year old man can still father a child with a 30 year old woman while the reverse isn't the case. Men are generally also more visual in their attraction and lets face it, younger looks better most of the time. There are of course exceptions but it is what it is.
