I really suggest you to create some options like: 1- the person being forced to identify himself in case of transgender... 2- have the option Search for Men, Search for Women and Search for Trans... Option to report and ban transsexuals and ladyboys who seek respect and equality but do not respect the space of straight people. It is very inconvenient especially in Thailand. Straight men who check the "seeking women" option should not appear as an option for trans and vice versa.
