compdoctor - i believe hermaphrodite and transexual are synonyms. but according to wiki, there's debate on the exact definition.

Bugbee and CWD - thanks so much for your input. Both of them seem to be saying the opposite.
Do you think it maybe be that guy/shemale is more targeted towards the gay / bisexual sector, while girl/shemale is more targeted towards the kinky straight sector?
