Friends

have you ever thought about why we get interested in the opposite sex? what attracts us? almost all of my boyfriends I met and I knew I wanted to try to date them but yet how do we establish substantial relationships with the opposite sex? siblings can be some, life long friends, friends of family, friends of siblings, etc. but in the teenage years every person of the opposite gender you become good friends with you eventually try to be with. so what is this equation for good friends of the opposite sex? is it just meeting them in a situation where you can't date them? or how can you make those friends without that type of meeting? I'm trying to figure this out as I go off to college. so how can we do this? I want to find guy friends I can just hang out with, meet up for coffee, play games, or do whatever with without the pressures of being a guy and girl alone. yes, I know there will always be tension but why more than the necessary? most of those substantial opposite sex relationships I have are either failed relationships, camp friends, family friends, or life-long friends. any suggestions.. more contemplation on this later.
