Just so you know, maturity can change a lot of kinks and sexual preferences. Also, when you fall in love, your kinks might change. Before I met my husband, I liked rough sex, but once I met him and fell in love, I enjoy more passionate and less rough sex. Sometimes we still turn our kinks on, but it is more of an emotional connection. Don't be too worried about her change in preferences. Also, she might have learned her lessons the hard way with precious partners about taking sex photos/videos.

Every relationship is different. If you want to try something different sexually, be open with her about it, but don't try new things just because you think that's what she wants. Communicate!
