The Other Drawer

I've been married for five years now and things between my wife and me are generally good. We have a happy home life and our sex life has always been solid, if not the most adventurous. Recently though, I started keeping this...other drawer in my nightstand. Inside is a collection of adult toys and magazines that I found myself drawn to during late-night browsing sessions. It's just little things I've seen online or read about and thought might be fun to try one day. The problem is, I'm terrified to tell her. She'll think something is wrong with our relationship if she knows. Is it okay to have these secret fantasies and curiosities? Should I share them with my wife, even though the thought of it makes me feel so exposed? What do you all think?
