Hi Ironicman - whether or not she means to do it, these comments are clearly affecting you and i would state outright that they make you feel uncomfortable and that if she wants to try new things all she has to do is say so; after all you're still learning about things yourself and the whole thing could be quite fun if you communicate to her what you do and don't want i.e have fun exploring together rather than being made to feel inadequate because of her past. Hope ive been helpful.
