Hello! I (27M) have been dating my partner (26F) for a little over two years. Our relationship began as an open one, as they lived with their partner who broke up with them after coming out as trans. In turn, we made our relationship monogamous.

Anyways, fast forward to today and we just had a long and honest conversation about them potentially being a lesbian. My feelings are obviously complicated since I at once want to help them be the best and most honest version of themselves AND I want to maintain the level of comfort and security that our relationship has.

We are considering having a threesome, as that would be a way for them to explore their sexuality while also maintaining our relationship. Afterwards, we've agreed to have a debriefing as far as how we both felt.

What advice do y'all have in regards to these discussions? Advice for having a threesome in a situation like this? Any other words of wisdom?

Thanks and I look forward to hearing what everyone has to say.
