We don't learn to "do stuff","hang out",etc with members of the opposite sex.
Then when we finally get to have an interest in (girls,for me)it's not for these reasons.It's primarily (most usually)for sex,and don't start calling me a sexist,I'm not.We may pretend to be wanting to be friends,hang out,what have you,but you know what the uktimate is.

*Giggle*
