Why do double standards exist in this situation and what am i supposed to do?

How come my boyfriend swears in everyday talk yet if i do he doesnt like it and says im a 'foul mouthed bitch'? Its the same with my dad, when talking he will be like f this and f that but if i do the same he will say its disgusting and 'not nice comming from a daughter'.

Also when discussing something my boyfriend says I 'answer back' when im only giving my point of view in a calm way. He also goes on about the way i walk he says im not feminine and walk from side to side i tell him thats how he walks and he says 'im a man' you walk like one.

I feel like its all to do with me being female im meant to be 'meek and gentle' or something but i didnt ask to be female its ****, id much rather have been male. Just wanted opinions/input :/.

Your boyfriend is an ******** with abusive tendencies. Lose him and find someone who doesn't rely on lazy gender stereotyping or try to control you.
