So I'm a bisexual female in a heteroromantic relationship with a man whom I thought was straight. Recently, he came out as bisexual and admitted to me he's been intimate with his male best friend before. And that they have been sexting recently.

When I asked why he never told me until now he expressed concern that I'd leave him for being attracted to men too. I had a long talk with him about how I love him no matter what and his orientation is not a determining factor of me being with him. Plus it would be extremely hypocritical of me to not date bi man as a bi woman.

Ever since he told me though, I've been actively fantasizing about him with his friend. They never did anything penatrative just oral and handjobs but still.

We are not 100% monogamous and we have had sexual encounters before with other participants. But now I feel bad because I can't stop thinking about how intriguing/exciting seeing him in a bi sexual scenario would be for me.

I do have a mental illness that includes hypersexuality ad a comorbidity and I feel like I'm spialing into that mindset.

I feel somewhat guilty over it though because my partner is going through the process of having just come out. I'm not sure how to navigate telling him how I'm feeling about everything. Obviously, i think he's amazing and so sexy, but I don't want him to feel fetishisized or anything because of my odd reaction.

We had discussed inviting his friend for a 3some prior to him telling me about their history. And I've know his friend was bi since we met. But I'm not sure how to being up the idea that not only do I not mind he's bi representing but also that I'd be thoroughly okay with us exploring that if he's interested.

I also have been feeling a strong desire to have interactions with another girl since I found out. I keep having dreams and imagining scenarios and im feeling like I'm having a sexual existential crisis.

I've never been in thw position of having someone come out to me and even though I did it it feels so new. I dont know how to navigate all of this.
