I had my second ever in person session with someone just a few hours ago and we agreed to try rope bondage. He put a chest harness on me and then tied my hands to my thighs. Right after he finished I started getting this super weird fuzzy sensation in my face, stomach, and hands. It definitely wasn't numb because I felt it in places that didn't have any rope near them. Shortly after I felt a sort of rush in my ears and I ended up asking him to undo the rope on my hands. The feeling in my stomach was almost like nausea but without actually being nauseous. After I was partially untied I sat down for a few minutes and felt fine. Afterwards we ended up using leather cuffs instead which worked great with no weird feeling.

I guess I don't know if that was an "entering subspace" sort of feeling but it was very odd and scared me cause I thought I might throw up or something in the moment. Thinking about it now it wasn't nausea it was just a tingling in my stomach. The reason why I doubt it was sub space is that it seemed insanely easy to get into. Literally just wrap rope around my wrists and I'm there. I tend to get very in my own head and struggle to calm my mind and relax which is why I freaked out and apologized to him like 8 times.

Has anyone ever experienced anything like this?
