TLDR; My boyfriend wants to share me with another guy, I like the idea as well, but I don't want it to change us or come between us in any way. New throwaway account to post this, as my bf follows my real reddit account.

For some backstory- My boyfriend and I have been together for a little over four years now. We get along great, we love each other very much, and we've always had great communication and are very open and honest with each other. Our sex life is great, we're both pretty adventerous and open to try new things!

For the past year or so he's been bringing up the idea of sharing me with another guy. I don't think he's exactly envisioning it as him being a "cuck". I think he more or less wants to watch without the humiliation aspect of it, so a stag I guess? Anyways- he's brought it up lots and lots of times, and not just during sex. He's also brought it up after sex after his "post nut clarity" *eye roll*, and during the day when we weren't engaging in sex.

I personally am very much on board with the idea, I think it sounds super exciting and sexy. We've dirty talked about it during sex, and even role played with it a little bit as well. We both get super horny when we dirty talk about it during sex, and I always end up getting really into it.

Now here's my problem. Neither my bf or I are the jealous type what so ever. He doesn't get jealous if I talk to guys that are my friends or guys that I've kniown forever, and he even is really great friends with some of my way back guy friends. However, I'm worried that if we actually do this he'll get jealous and it will end up hurting him bad or breaking his heart. I wouldn't want this to change how he looks at me or thinks about me, and most of all i wouldn't want this to push us apart or make him resent me.

He swears it wouldn't change anything between us, and might even bring us closer. He says he won't get jealous, and if he does it'll be a "good jealous". I love him so much, and I don't think the experince would change how I feel about him in any way at all, but I have no way to know that for sure.

Any advice on how to proceed, or if we even should? Anyone who has experiences in the past similar? Please help lol. Any advice or insight in appreciated, thank you!!:)
