I've been with my partner for 6 months. When we first started seeing each other, we discussed our desires and hard limits.

I've always been in monogamous relationships, and told him that threesomes involving other women were a hard no. He respects that and doesn't ever bring it up. He did however ask me if I would consider a threesome with another man. I told him this didn't really interest me, as I am afraid of causing any damage to our relationship. I'm very happy and see us being together long term.

He has never pressured me whatsoever, but has mentioned a threesome with another man a couple times in conversation. And over time I've been a bit curious of what it would be like.

What I'm looking for insight on, is this. When I think of him with another woman, I find it unbearable. So I'm trying to understand how he could not be hurt by the thought of me with another man.

I plan on asking him this the next time he brings it up, but I would love to have some insight on others thoughts and opinions before I do, as I know nothing about these things.
