No it's not a girl playing male characters or vise versa, that much I know. Besides it's just a rp character, the only thing I find weird is if they miss-use the gender of wolf characters to get a sertant rank or mate. Then it's just plain wrong...

(defenition found on wiki)
Shemale (also she-male) is a slang term frequently referring to trans women with male genitalia and augmented female breasts from breast augmentation and/or use of hormones.[1] The term is considered derogatory by most trans women.
The term she-male has been used since the mid-19th century, when it was a humorous colloquialism for female, especially an aggressive woman. It was also briefly used as an exclamation during The Great Depression era United States, before eventually settling into its current definition.
