<human>: Give me a shortened version of the text

I [16 M] recently met a Friend of my cousin's. We'll call her Marissa[15 F]. From the moment we met, She constantly wants to have sex. She doesn't seem too interested in dating. I want to date. 

She isn't slutty, she doesn't act like that with anyone else and never acted like that at all prior to meeting me. 

Im particularly frustrated because I am usually very good at reading people and knowing what they want but I'm stumped now. How should I try to convince her to go on a date without effecting our life in bed. Because the steady sex is pretty great
<bot>: I want to date a girl, she just wants to have sex. How do i convince her to go on a date or two?
