Are there any bisexual ladies out there with a boyfriend who have successfully experimented with another girl AND had their bf participate?

I'm not trolling, just genuinely interested in making this happen but I want to hear some other people's experience with this. By successful I mean all parties involved enjoyed themselves, no hurt feelings ensued, and you remained a happy couple afterward. ACTUALLY, I want to hear your stories regardless if it was successful or not. This is not something I have proposed to my bf yet, and I would like to know the worst that could happen in this situation.

xpost- I didn't know this subreddit existed!
