Threesome?

My boyfriend and I talked long about the subject and surprisingly it was my idea to start looking for a third.

For a bout 2 weeks now we’ve been looking and got lucky to find someone but haven’t met up yet.

I guess where I I’m going with this is have any of you gals had a threesome with you’re SO? If so how did you go about finding a third? How was the experience?

I have all the questions and I’m just curious.

I know the friend option but I told him straight up that I am not sleeping with any of my friends. Even though a lot of people say it’s easier; for me when I think about it it’s like incest in my head...

But anyways I just wanted to get opinions, thoughts, advice, stories.
