Shivering during scenes at a dungeon

Hello,

I am afab (26) and this is my first ever post on Reddit, so I apologize if I do this wrong. A few months ago I started exploring kink with an experienced Dom. We currently do our scenes at a public dungeon and I started recently shivering a lot during scenes. I am nearly entirely naked except for a thong and the rooms are pretty open. My Dom is really good about pivoting the scene to either cuddle me for warmth, move me around, or place towels down on cold surfaces before I lie down or kneel on them, but it does little to stop the shivering. I feel a bit cold, but I don’t feel like I am cold enough to explain the intense shivering. I’ve read that it could be adrenaline or nervousness (though I doubt the nervousness). I didn’t really deal with the shivering in our first or second scenes, but now it feels like it has gotten more intense (the shivering) as we’ve continued. I’m mainly writing this post to hear about other people’s experiences and to see if there’s anything else that could help from people’s recommendations.
