My husband of 3 years is asking me to have sex with his co-worker
We are a couple [F26 & M28]. First of all, my husband and I have sex regularly around 2 times a week, and I was satisfied and believed that we had a good marriage relationship.
Recently, my husband has been inviting his co-worker over for dinner, and he is a very pleasant person and I found a lot in common with him, he is very into fashion just like me and we connected very quickly.
Although I haven't known him for a long time, he proved to be a good friend and often came over for dinner. He and my husband seem to have a very good relationship.
I was shocked when my husband suddenly asked me before going to bed last night if I would like to have sex with the co-worker. I was super surprised and I will say that I will never cheat on my husband and play around with other men behind his back. But he was very insistent and asked me if I would like this. Obviously this was sudden but apparently my husband has a "cheating" fetish, or I think it is called cuckolding? I want him to enjoy our sex life as much as I do and so I listened to what he had to say about this.
He says he had asked the co-worker who reluctantly agreed but only if I also agree. I'll be honest and say that I am open to anything that my husband wants me to try, but at the same time this is something that is new to me. I told him that I'd think about it and tell him in a few days.
Obviously I didn't get a good night’s sleep as I was thinking about what to do. Today my husband told me that he didn't want to force me to do something I don't want to do and that he wants me to take it slowly like going on a date first and take it over time if I preferred. He also told me that he is fine with me doing it even if he is not around, but he'd prefer to be able to watch... I'm still unsure of what to do but I do want to make my husband happy.
I haven't said if I would go along with it or not yet. But I have talked to both my husband and his co-worker together about it and both of them says that I am the one with the decision and it is all up to me. What should I do?
