I'm somehow reminded of the Brothel For Slaking Intellectual Lusts from Planescape: Torment, now.
Anyhoo. I do agree that men are somewhat less forthcoming with their feeling and personal issues than women... but, I've still had plenty of close male friends who were willing to engage in "mutual self-disclosure".
Admittedly, though, this is because I tend to end up being friends with "moderate" guys, for lack of a better term. I don't tend to hang out with overly "macho" men, either.
Peace & Luv, Liz
