I think her body hair is a turn off
Why is it a turn off?
I don't know, I just dont like that.
It's normal to not get attracted to girls who have body hair. Your life your rules i guess.
I'm going to try to get her to shave for me.
While it's understandable that you don't like body hair girls, you should not make her shave for you. As you have a right to dislike things, she has right to do with her body whatever she wants. You can talk to her about it and let her decide what to do.
