I got "caught up" in a 3-way years ago. There was a woman in my town which, anyone can tell you, was the prettiest woman in the town. I'm not really attracted to women, but because she showed some interest in me, I decided to go for it and go to her house with her. When we got there a man was sitting on the couch! I asked her who is that? She said "Oh don't worry. He's my husband but he doesn't mind." He doesn't mind?! I'm in the man's house with his wife and he doesn't mind?! "No," she explained. "We're not exclusive to each other. You want something to drink?" If course!
I went to the bedroom with her, sat on the edge of the bed and started taking my clothes off. Just then her husband comes into the room and says, "I'll be in in a minute. Just let me wash up." He left. "Excuse me?!" I asked his wife. "Oh," she replied, "he'll be joining us." Me? In a threesome?! I mean, I'll try anything once, but this was going kinda far! What could I do? I was in the man's house getting ready to get jiggy with his wife in his presence! I had no choice. A threesome for me.
Later, she explained the only way she'd give her husband sex is if he paid for it or it was something kinky like a threesome. Bizarre.
We'd fooled around but basically I couldn't perform because I was too nervous. Anyway, even though I've been with women I lean mainly towards men.
