Supporting more than one team?

Opinions? As a native Englishman (sadface) I have to support my local team, Birmingham City. I go down there every week and watch. But my heart belongs with Barcelona. It has been for years before I even began supporting the Blues. And then recently I picked up my third team, Bayern, I remember watching a match a year or so ago and thinking wow, and I've followed them since.

It gets worse internationally, because I don't support England, never have, I've never felt any connection with them. I support Spain above everything else til the end. And understandably, I do have my other teams I'd like to do well, Germany, France, Poland.

Any of you guys in this predicament? Both domestic and internationally?
