I've been doing a lot of writing mostly when I'm not wasting time or working on other things. As many writes will attest to, writing for the opposite sex can be difficult. I do my best to model female characters off of real women I have known. And sometimes I will ask a woman if the writing seem to be on par. I've done some online research with little help in that they tell me mostly what I already know. Sometimes I will call myself clever while writing dialog for a woman by extending what she has to say. Women use twice as many words as men, right. So I will at time use twice as many or simply more word to get the point across than I normally would if I were speaking or most male characters saying the same thing. I try to cut back on direct and fragmented speech and make them more articulate even when they're not very articulate compared to most people. Feelings as well as thoughts would be behind those words. Another so called cheat I would use at times is to make the men almost like testosterone fueled robots who will speak in macho clichés and three to four word sentence in comparison to the female characters. Sometimes I will have 'wordy' male characters but in my mind they are 'that guy'. That guy who won't shut up about himself and every opinion he has or that guy who wears his heart on his sleeve and always wants to talk (complain) about his feelings. I made 'Derek' into a mix of 'heart on his sleeve/testosterone fueled robot'.
The real difficulty with writing SMNP is she is a deliberately stereotypical hyper sexualized femme fatale character. It's like writing a thousand 'Samantha' from 'Sex in the City' characters rolled into one (come on, everybody knows Sam is the slutty one). I am avoiding a lot of the given tropes about such a character, example: "the femme fatale cares mostly about men and not so much about women; rarely has female friends mainly because of jealousy and FF inability to relate in ways other than through sensuality and sex."
whereas SMNP actually seeks out female friendship for that very reason. She wishes for other women (especially her super powered colleagues) to see her for a normal person at heart even though her body and mind are hyper sexualized near to the point of uncontrollable. 'With great power comes... yada, yada, yada.' It can be very difficult for her explaining why eventually she WILL try to make a sexual pass on you, your friends, your partner and just about everybody else you know or even see. SMNP informs them to just keep saying no until she gets it out of her system. In that sense she has a standard ff quality of striving for love, approval and social acceptance but it's for the platonic companionship of other women. SMNP finds men to be fairly boring at times as her powers allow her to read men like a book beyond the normal tells that men with typically give away. Most of the time she sees them as pets or something to be treated as a pet. As with Derek, SMNP a special relationship primarily due to her alter ego, Fumie. Because of that SMNP tries to see him as more than a pet but as a true friend but old habits
always die hard and she continuously claims 'ownership' of him.
