@chyna Has got my drift.
As a guy, I can say that we do become mature, but the first step towards maturity takes long. (We do catch up though, so don’t worry). In the end though, there will be differences and you’ll need to accept that. Guys do things girls think are immature, and vice-versa (very crude generalization, I know, but its a general point).
As for what @meagan says, I agree with the advice. Don’t let that happen.
However, most people do have a life outside of getting laid (at lest indirectly). Otherwise, I wouldn’t be the geeky guy I am, it surely doesn’t help me with the ladies. So have some hope, but be careful, as in all things in life.
