Why is she so immature about sex when she's not a virgin?

Whenever anything sexually is mentioned she goes 'eww, gross' Even though she's 18 and had sexual encounters She's been like that for years, thought it might just be a young immature thing but it seems not.. Even when were watching a movie and theyre having sex she's covers her eyes and says ew And when we talk about guys she says stuff like this guy was talking dirty to her etc and she says it like she's disgusted by it, but then she talks dirty back, I'm open to her about everything so it's not like a taboo subject It's seems really weird to me, and its actually quite annoying why do you think she does it? The only thing I can think of that she does it is to seem innocent? Posted from TSR Mobile
