I Tried a Kink My Partner Doesn't Share

My husband and I have been together for five years. We've always had an open relationship when it comes to talking about our desires, but there's this one kink of mine that he doesn't share. It's something I've wanted to explore for a while now, and being in the military means long periods apart can make these kinds of fantasies feel more intense. We'd talked about this before he left on his last deployment. He was okay with me talking to someone about it but didn't want to do it himself. It's all consensual, of course, but still felt like a weight I needed to confess. Anyway, when he deployed, I reached out to someone who knew my desires. We agreed to meet up once in person and then mostly online from there on. The first time we met, we were both nervous yet excited. We went to this secluded cabin in the woods that had a private room for our session. He was dressed as a doctor, which set off all sorts of things in my head. The room was dimly lit with soft red lights and a bed positioned near a window. There was medical equipment lining one wall; it wasn't scary but it made me feel like I was somewhere else, somewhere private and safe for this kind of play. He had gloves on and sterile instruments laid out nearby. When we started, he examined me like a patient would in a regular appointment. Checking my vitals, talking about how I felt that day, then moving into more personal questions. It got to the point where it was time for a physical exam. He made me undress first and lie down on the bed. I spread my legs for him and he began with basic checks, looking inside, listening to heart sounds through my chest cavity. Then came the equipment. He had these rubber speculums of different sizes that he introduced one by one into my vagina and then rectum, talking me through how each felt as they opened up space within. I was nervous but also incredibly turned on, the mix of being treated like a patient while feeling this deep arousal was something I hadn't expected. He used a few instruments to check other parts too, always explaining what he was doing and asking if it was okay with me first. We went back and forth between medical checks and play for hours that day. It's something I crave now and hope we can continue after my husband returns. Knowing his comfort level doesn't mean it has to stop me from exploring these fantasies. This session just feels like a chapter I needed to write, one where I was allowed to be vulnerable in ways outside our usual relationship confines.
