Which arm do you wear your watch on?

So my girlfriend has this theory that gay people generally wear their watches on their right hands. Although she has mostly been right in regards to gay people I still dont buy her theory completely because I havent been paying attention to straighty's watch wearing. So my question to you all is, do you wear your watch on your left or right arm? Let's see how her theory holds up with a much larger scale of gay people here on AfterEllen! Thanks for participating! :)
