My name is Sharon, and I'm male. In israel, where I come from, it is a name for both girls and boys. Since I came to study in the USA, this has been the source of frequent confusion. Everybody that I correspond with that hasn't met me, is of course convinced that I am a girl. I even get a taste of Chauvinism once in a while in online chatrooms or discussion lists.
When I had to get a social security card, I asked the guy to enter my name as Charon, so as to avoid the problem. This has only made matters worse. Now the DMV (god bless them!) won't give me a plastic ID because my social security info does not match the name in my Israeli passport, which is spelled Sharon.
