I would say that yes it is possible, but not very common at least. I only have one friend who is a girl who I haven't at least considered banging. I know that sounds crude, but it's the truth. We've known each other since the womb, and she is almost literally my sister (she lists me as her brother on her FB page
). Every other
attractive female friend of mine has either had feelings for me or vice versa at some point during our friendship. But that's just my experience. I'm sure someone who claims to be an "asexual" or whatever would have an easier time with it.
And btw, I am still friends with the majority of the girls I've dated in the past, for one of two reasons: (both are true)
1. I genuinely care about some of them, and still love one of them.
2. I believe there is the possibility of a "future" relationship still lingering, and I am still physically attracted to them.
If you're not physically attracted to a girl or guy, then it's a
hell of a lot easier to view her/him as "just a friend."
As a counter-example to mine, I have a friend who seems to instantly fall in love with any girl that gives him the time of day. I feel sorry for the guy, because this makes things terribly awkward around almost every girl he knows.
So I guess it just depends on the person. ^_^
