We have been together for a year. We started out fully non-exclusive for several months, before things got complicated and we decided to be monogamous.

We are both bi-sexual with very little experience being with the same sex (only a couple times each).

Recently she has mentioned that she would potentially be interested in exploring being with women again, and was wondering if I feel the same.

She says that we could do this together e.g. a threesome with another girl. However, I think she would also maybe like the opportunity to do it 1-on-1, but also would like me involved (and realises this would help with feelings of insecurity)

I guess a lot of guys would be very happy to hear this, and there is a part of me that's interested in exploring it. But I'm not sure how I feel.

Of course it would also mean that I could have the opportunity to explore a little bit more sex with men, which is definitely something I've thought about. However, I feel like I don't necessarily have the biggest desire for this right now - although I am definitely curious.

She has said to me that it's not a deal breaker to her, and that she would rather be with me exclusively than not be with me and get to explore this side of herself. But she just wanted to see how I would feel about it, and whether I would be interested

The thing is, there's also an insecure part of me that worries that if she truly loved me enough, she wouldn't want to be with someone else, even if it's to explore with a woman.

I know it's a bit hetero-normative, but honestly I WOULD be a LOT more upset by this if she told me that she also wanted to open things up to be with men aswell.

I'm really not sure what to do here, and I can't help but feel a bit hurt, even though I am also slightly interested by the idea.

I don't know if I should work through the slight insecurity, as this could be something very fun and rewarding for us both I am feeling insecure, but I am also slightly excited by the idea to explore more with men and of course have a threesome with her.
