The thing is both of us are straight and he is thinking that we could have a 3 way relationship where we would be living with another girl and we wouldn't have sex but he would have sex with both of us. I asked him if he would be okay with me sleeping with other men and he said no. I feel like this is kinda unfair but im not sure my feelings are valid. He has a way higher sex drive then I do so its hard for me to keep up so I see where he is coming from in that viewpoint. I would like to try having an open relationship but he's extremely jealous when it comes to the thought of me having sex with another guy. I dont know... Thoughts?
