Is it normal for my friend to act like this when it comes to boys?

one of my friends in school, she is a cuple years younger than me. ( I'm 18)she has never had a boyfriend or kissed, but she tells every body that she has, she has only told me the truth (she seems to only trust me, and considers me her best friend, to be honest I don't feel the same way, she is just a friend).
seen as every body thincks she has had a Bf, she gives others advice,and every body seems to look up to her.
all she whants to talk about with me is boys, what makes it worst is it's realy soppy romantic stuff , buquets of flowers, candels and fidelity rings and all that junk, that se seems to think is what having a boyfriend is realy about. (most reationships that me and my friend have had wheren't so Idelic, if you get what i mean) she waches wayyyyyyyy to much twilight and titanic, and thinks it's realy like that. she knows next to nothing about sexual stuff, like a few days ago I was like: oh come on! you don't know what fisting is??. wich I think is not very good seen as most boys her age are all ready interested in sex.
but I don't realy have the heart to tell her what me and my friends real life experiences. so I just tell her about a few romantic stuff I have done ( boyfriend buying me flowers :P thats the best I can doo).
then se asks me for advice and honestly I get fed up about it because I don't realy care that much about boys, and i rather talk about other things.
then she gets upset because she can't find a guy who likes her, (she kinda sucks at making a move) and says I'm not helping her enough.
then some times I cach her giving advice about boys to other girls and it's practicly the same stuff I told her.
Is it normal?? what can I do about it? she is realy starting to get on my nerves now, but I don't whant to be mean to her.
