My boyfriend (24M) and I (26F) have the best relationship, we are very communicative and openly share our different kinks. I’ve lately been thinking about a threesomes and the idea of my boyfriend with another woman turns me on. I’ve discussed it with him and I’ve told him that the idea of seeing him with another woman and seeing how much he wants to pleasure the other woman, especially if he’s slept with them before or is his type- turns me on. After fantasizing about it a couple times, he started to become more open to it. The more he started becoming open to it and wanted to actually do it the more I became apprehensive and emotional. I could no longer handle the aftermath of how I would feel seeing him with another woman. I never was an insecure or jealous woman but lately I’ve not felt the most confident and I think this could affect that as well. I know deep down I can’t go through with it but the thought still turns me on. We still talk about it in bed and it makes us climax but right after, I feel regret which makes me want to never try it. Idk what’s wrong with me because it still turns me on but I don’t think I’ll ever try it. It sometimes says he agrees to talking about it more because he thinks I like it and always after the end of it he reassures me that he wants only me and loves me. Which honestly is great, couldn’t ask for a better partner. But I’m confused about my feelings . Are others in the same boat too?

TLDR; I started talking about threesomes to my boyfriend and he’s into it but I no longer want to entertain it because I don’t think I can actually see him with anyone else. We still fantasise about it but idk why something I don’t want to do; turns me on.
