Hi, sorry for the delay, I just joined the forum some days ago. I think showing random videos for her could be an interesting door to your real fetishes. Of course, would it be better to start with easy ones. When this become a habit, then you can introduce slightly harder videos from social medias (even from things your not so much into) and then BOOM: send her a video that is exactly how you wanted it, one of your favs. See how she answers, i think the familiarity with the theme will help her not overreact. If she does, and say to you she doesnt like it, then all hope is gone. You also can use some joking tone like "no way you're going to do this to me" or "omg, this one is far beyond". The reverse psychology of joking can make she think it would be "funny" instead of "strange". That's the way I got to make some amazing vanilla girls to make my fetishes come true. But here is a tip: its not for everyone.
