text: is it weird for an 18 year old guy to go out with a early 20 something girl? probably not but you see a lot of girls going out with older men and now we are used to it....but you dont see too often a younger man going out with and older woman....if there something weird do tell.....i wanna know what you people think no, i don't think so. i always thought men should go for older, more experienced women. just don't act like an idiot, and please be mature. women mature faster than men. my boyfriend is five years older than me and we are about the same level of maturity.
