Hello. I'm still new to this site, but thought maybe I can get some answers and helpful tips here.
My primary partner of three years asked me if there was anything I'd always wanted to try. I was reluctant, since I am a very shy person and haven't told anyone certain kinks about me before. I told him I wanted to try a threesome. We talked for a few days about it. Rules, what I want to feel during it, what kind, etc. I was shy, but pretty comfortable during it. But now I regret ever telling him that side of me.
What happened was we had a very important rule-- that I am not left out at all. I don't want it to feel like it's just them (and of course not just us, like, I wanted the three in THREEsome). But long story short, we had fun with her, then went to the club for a few hours, then headed back to the hotel.
Now, I was on my period, but we all still found a way for me to be included while having fun. He did said something along the lines of, "Hey, let's shower together, since it won't be messy, and we can have a little us moment, since you couldn't be included completely before." I was happy and went to the bathroom. While I started the shower, he had sex with her for 30+ minutes. I showered, took off my makeup, did all the skin and body care, and just heard their moans repeatedly over and over again. I felt sick and completely forgotten.
Fast forward to a few months, I've forgiven him, but now I'm struggling with the fact that maybe I can never explore my kinks. I'm trying to learn how to live with the pain. I still love him, but I just can't forget little me in the corner of the bathroom, hearing a man I love making love to another woman, completely forgetting what he said to me 5 min beforehand. I've been crying a lot more lately. There is some more to the story, but I'm already at my mental limit, typing this out. Will add clarification, if needed, in the comments. Thank you for reading.
