Generally 2 years older...so 21 at the moment, I want to be at the same stage of life as me at the moment just logistic wise in a relationship it's easier to manage and compromise, but I'm sure when I get into the real world this will increase, probably keeping within the 10 year interval though e.g. in my twenties I'd date someone in my twenties, in my thirties someone in my thirties ect.
