Hi everyone, I am in unfamiliar situation right now. I am a guy in his early 20’s and I have always found threesomes interesting but I got approached to do a threesome online and they (M36 and F36) seemed good looking and friendly about it. I told them I was straight from the start but have never been with a guy and a girl together but I would be open to the wife and with the guy sucking me and letting me fuck him but that’s it. The wife later mentioned that if I want to join them together in a threesome, I will have to fuck the husband by himself. I have been curious about doing stuff with a guy but not sure if I’ll like it and wanted some advice about this situation. While I am very curious and sometimes turned on, my gut says that I should just unmatch with them for kind of forcing me into a position I’m not too familiar and mostly comfortable with. Any advice is appreciated!
