A Strange New Feeling Inside Me...

I’ve been dating my partner for two years now, but it wasn’t until recently that something inside me changed. We've always had a good relationship, but lately I find myself thinking about ... these strange ideas. It's hard to explain, and even harder to admit. Maybe you've felt this way too? Sometimes when we're intimate, I have these thoughts of him being in charge, not just physically, but mentally too... like he’s my guardian or something. It started small with a few jokes about it, but the more I thought about it, the stronger the feeling became. It's not that I don’t love him as an equal partner; I do. But there are moments when I feel so vulnerable and ... needy? That maybe I want to let go of some control... be taken care of in a different way. It feels odd talking about it, but we have such open communication that I decided to share this with him too. His reaction surprised me; he said he had thoughts similar to mine sometimes as well! We agreed to explore the idea gently at first, trying some role-play scenarios... He’s much more experienced in these things than me and suggested a few activities. It was surprisingly enjoyable, but also made me feel conflicted. I'm not sure if what we did is normal or just us being weird... So, am I the asshole for having these feelings? Is it normal to want this kind of dynamic with someone you love so much...
