The New York Times has an interesting article on friendships between gay men and straight men.
I have a fair number of straight male friends, and they do some of the things mentioned in the article, like asking me for advice about women. I also hear a lot more of their soft sides-- feelings, insecurities, etc.-- than they share with their straight friends. They'll say something like "You have to promise not to tell the other guys, but ...."
I'm a fan of difference. It keeps things interesting.
Anyway, read the article.
