I absolutely adore my male friends! I was friends with my husband for 16 years before we got married. We've been married for over a year, and I'm still in touch with 3 of my past male friends, who live in different cities (so it's just monthly emails, and visits every couple of years). I love my girlfriends, too -- for a whole different set of reasons.
In "When Harry Met Sally", they were attracted to each other, they had sexual chemistry. That chemistry isn't active in every friendship which leads me to believe we can just be friends. I think it depends on the people and their circumstances, too.
