I have extensive experience in BDSM from before I met my wife which was 19 years ago. Mostly in a Dom role. I had a few subs who enjoyed choking, I did it but never felt comfortable because I always feared hurting them. I always thought that it's something I would not want to do as I hate losing breath. My wife and I have dabbled in some light bdsm play. Light spanking, using restraints on her etc. Even light choking on her. I have bad ED so we use toys, fingers, my tongue. I always focus on her satisfaction and pleasure first before taking care of myself. Last time we had sex I was stroking myself after she came as normal. She likes to stroke my chest and face as I do, and loves making me suck her fingers. This time she did that but then put her hand on my throat and squeezed gently. I didn't know if it was purposely choking at first but it drove me crazy and I became vocal about it, causing her to continue to do it squeezing as I came. I was embarrassed because I never imagined I'd like it. I want to ask her if she meant to do it but I don't know if im reading too much into it. I've also asked her to take control but she said she can't but more and more it seems like she is opening up. Any advice you can give would be appreciated.
