Husband confessed fantasy

My husband has recently told me he for years now has fantasized about other men f*cking me. Says he would watch, join, says he wants to see me pleasured by other men. I was caught off guard but am not completely opposed to the idea either. I am curious if he’s had this fantasy for years if he has a specific person he’s imagining this with or if I would even want to know that. I’m having very mixed feelings since he’s told me this 🤣
