You mean polyamory? Yes, I've done it. No it wasn't worth the pain. I wouldn't do it again. Apparently I'm too jealous of a person, well, technically speaking she was the only one allowed to "date" somebody else. Only after me egging it on (cause it's kinda hot if you think about it hard enough) did I learn that she had already cheated on me with him a week beforehand. My bed was laid out though and I had to sleep in it. I already watched them have sex (yes, I'm bigger than he is) but she also betrayed me. What else was I supposed to do? I was okay enough to watch them have sex in front of me, but the betrayal was almost too much to handle. I allowed them to have sex like 2 more times total before the betrayal actually ate me away and I wanted to end things. Funny part (well not funny) is he was a virgin and she took it from him (we gave each other to each other), so he "fell" hard for her, and I hope he drinks himself to death because of it. Dirty rotten bastard. Oh yeah, forgot to mention, he was also one of my best friends too. Ha, friends usually stab you in the back when they want some pussy. All my friends now are women.
