So my that I've been on and off with for some special reasons. Wants to have a threesome. And I don't but he keeps pushing me for it. I don't think that if be good for it and I'm afraid that I'd watch my own boyfriend have sex with another girl while I sit there and watch. He says I wouldn't be left out. But I'm nervous and honestly when I think about it. It's kind of like cheating. I'm sure you all see it differently, but I don't like to share and I don't like the idea of him even considering to wanna be with another woman! I'm not sure what to do or say to him. Any thoughts?
