I'm Not Sure If This Is Normal...

It's been three years since I started dating Sarah. We're in our early 20s and have a really great life together, two jobs, pets, the whole thing. Last week, she suggested we try something new in bed... Well, more like something I've secretly wanted to do for months but was too afraid to bring up. I didn't want to pressure her or make things awkward. But when she brought it up herself, I felt relieved and excited. She asked if I ever thought about toys during sex... You know, stuff that helps enhance the experience. And suddenly, the hesitation vanished... It was something I had in my drawer for a while, just waiting to be used. As soon as we agreed, I brought it out. We started slow, but she encouraged me to try different positions and intensities. She loved it... more than expected. But after it all, there's this lingering guilt eating away at me. What if I'm the only one who really enjoyed that? Should I be honest about it or keep quiet? This is starting to feel weird... What do you think? Am I overthinking this? Is it okay for both of us to enjoy different things even when I'm not sure how she feels about them...
