At what age does your preferred gender peak in attraction?

I think for women it is early 20s. I'm 25.

Edit: I've added a poll which shouldn't be taking to seriously as I am sure people will have different views depending on their age. Moreover, I am sure some people prefer a variety of ages and indeed both sexes. However, it is all good fun!

Put the internet to work for you.
