Arggh! Please help me guys! just suggest whatever you want :(

the theme is gender bender where main character turns into opposite sex.

i've been thinking of a playboy who turns into a girl or a man hater who turns into a boy.. i cant decide which is which

Matriarchist (like sexist female but more of a social dominatrix) that turns into a male because a waiter of a restraunt she goes to often was a wizard and turns her into a guy to let her see why her opinion may not be socially accepted. Therefore, he turns her into a guy until she sees what being a guy is really like and how her matriarchism is not very cool to him. And all the while, she/he could be coming to grips with societal differences of genderdemographics as well as how differently the standard males act compared to standard females.
