I had a conversation with my LTR and she told me that if the moment is right and she's heated up for a girl, she'd definitely have sex with her because it's just experimenting and not really cheating. It might be a great revelation to be honest because it could lead to a lot of sexual experiences which I want.

But I realized I have done a horrible job at vetting her. I realize she can be a great fuckbody now, but she's nowhere near an LTR material. The fact that I really do have to tell her that it is cheating, what else is there that I need to tell her that is not wrong or "cheating"?

What do you think about demoting someone like this? She'll probably not be okay with me plating her and will break, but it's either she'll be a plate or nothing for me.
