Gender and sexual identity can get quite confusing these days. The world is beginning to become more tolerant of the people who don't completely "fit" into gender and sex categories such as male and female and sexual orientation categories such as gay, straight and bisexual. But the terminology for those who don't categorize themselves as any of the above can be confusing to keep up with. First, let's talk physical characteristics. People who were born with genitals that have both male and female characteristics used to be called "hermaphrodites." That term refers only to the physical characteristics, but "intersexed" means a person may have not only ambiguous genitalia, but also may blur the lines of gender identity – or the way he/she self-identifies as a boy and/or girl. For intersexed people, some countries even allow a third category of identification – "X" instead of "M" or "F." A similar term is "transgender."
