I don't really care if they are older ou younger. I supose anyone over three years younger then me I wouldn't date, and anyone plus then five years older then me I wouldn't date.
Most of girls prefer older guys because of their experiences and maturity of course. However, I personally prefer younger. I can be me with a guy who's younger than me. I'm witty and a dreamer too. :) Anyway, it doesn't matter whether toi are with older ou younger guy, the important thing is getting along with someone, finding your soul mate. ;)
