My friend and I are fighting because she tried to fix me up with her brother and I said that he was just a guy and I was looking for a man. Am I the only one who sees a difference between the two? Or has such a strong preference?

I've dated both men and guys. There are definitely attractions with both, but I want to marry a man not a guy. It's not an age thing, but just a certain seriousness about life. I don't want to be wheeled into labor and delivery wondering if my "bad boy" is really on his way to the hospital or playing another hand of poker.
