Post-Divorce Kink Exploration Mishap

So I recently went through a divorce after about five years of marriage. It's been tough but also liberating in many ways. One area that's felt incredibly freeing is my exploration into the kink world. Before, I was too focused on keeping things tame and conventional with my ex-wife, who wasn't much for anything kinky at all. Now? Oh boy, am I diving deep! I met this really cute girl named Mia online through a kink-friendly forum. We clicked instantly over our shared love of roleplay and teasing games. She's in her late twenties and super fun to chat with. We decided to meet up after getting to know each other for a couple weeks, which was totally consensual on both parts. The first few dates were really innocent, dinner, drinks, stuff like that. So finally we moved things along to an actual bedroom encounter at her place last weekend. I thought she might be into DDLG or something strict like that based on our chats, but turns out it was more playful teasing for me and then just regular fun sex after some buildup. Anyway, there's this one moment where I accidentally called out 'Mommy' instead of Mia's name when we were doing things, I had a slip of the tongue! It was totally not my intention to play that out or suggest anything with her. She laughed it off and said she thought it added another layer of fun but didn't want me pushing anything like that. Afterwards, though, I felt this weird tension. Was there something wrong with my reaction? Did I come across as more into age-play than I am? Should I have corrected myself right away? Now we're in a kind of weird limbo where it feels like there's an elephant in the room, not sure if it's just in my head or Mia really picked up on that 'Mommy' thing and is now uncomfortable. And yet when I try to bring anything serious up, she laughs it off as no big deal. Anyway, this whole kink exploration phase of mine has been eye-opening but also a bit confusing at times, especially when you're new to something like this after years of being married. Wanted to vent here about that weird moment and how I'm feeling awkward about where things stand with Mia now. Hopefully it'll help me sort my thoughts out!
