Finally actually considering a threesome (2 girls, 1 guy) but am unsure of boundaries
After a week of my bf insisting and nagging, I have finally agreed to try a threesome with him. It will be with his best friend since childhood, so we both know him well and are all friends. The problem is that I have absolutely no experience with this, so I don't really know what is considered appropriate and inappropriate here. Does anyone have any experience with this sort of thing?
My main concern is that my bf will get jealous. He already is, hence this threesome in the first place. I don't think he really wants to do it, but his friend and I are physically attracted to each other and he thinks I'm going to end up having sex with him anyway, and he doesn't want anything going on behind his back. I'm afraid that if I end up really enjoying being with his friend, and I show it (which I probably will), he is only going to end up being more jealous. I'm wondering how much to balance things between the two of them. Like should I try to be 50-50, or should I make sure to give my bf more time, like 70-30 or something? Or should I just wait and try to pick up on cues and follow my bf's lead? And what kind of things should I feel comfortable doing, or should I also just wait for them to guide me?
We're planning on doing it sometime this week, depending on our schedules, so I need some advice quick. I'm getting really nervous and scared about it. I actually think it's a stupid idea and don't really want to do it, but I am VERY physically attracted to this friend and so I'm really afraid of what might happen, and the kind of impression it will leave on my bf.
