It may sound like some kinky S&M shit, but it's not.  Maybe some of you know what it is.  If not, let me explain.  The Man Vault is for man secrets.  For men, by men.  It's the place your buddy can go and tell you all of his secrets without fear of you going to tell your girlfriend of wife.  It's like confessional but without the touching and molesting of little boys; unless of course that's what he's confessing.

If he cheats on her, shut up about it.  Tell him how you feel, but don't go running off to your girlfriend (or wife) and rat the guy out.  Don't be a spineless pussy.

In fact, there's nothing you should be telling your girlfriend.  When your buddy tells you something, really no matter what it is, you should basically keep your mouth shut.  Keep your gossip at a total minimum.  Actually, 'gossip' shouldn't even be part of your vocabulary.  Guys shouldn't gossip.  That's what chicks are for. 

And girls, if you find out that your boyfriend didn't tell you something, (and if it didn't involve you at all) then shut up and understand that guys don't talk about their friend's problems or issues.  We barely talk about our own feelings, so why should we talk about anyone else's.
