I've been there more times. Three, four and more somes. The first time was totally unplanned and I really was flabbergasted afterwards (it was with my best friend at that time and her boyfriend). We were all watching a movie and she started to kiss me and well I just did what felt right at that time. She asked me if I agreed to let her bf join in and I said yes. Afterwards I was confused, excited and more I can not put a label on. It happend a few times after that (until my bf at that time wanted to join in then it stopped, they just wanted me not him). I had an open relationship btw lol.

My ex husband and I had an agreement before we got married, and we tried out all sorts of things (not on BDSM he was not in to *that*). But after I got pregnant I changed alot and I didn't feel like sharing my body with anyone but my partner anymore. Well ofcourse he had a different view on it and he still did it even when he knew I didn't agree (he just *forgat* to tell he did something).

Point to my story is you really have to be in a stable and open (communication wise) relationship for this. Ask yourselves how jealous you really are? Can you handle it when the third party has more feelings then just the lust part for either you or your partner - or worse- if you or your partner develops deeper feelings for the third party?
Cause it all seems like fun and really horny if you fantasize about it, but reality is more complicated then fantasy. You have to set boundries and make sure you all understand them.

Good luck on your decision.

ps. Three somes are better in my opinion then four/more somes, it gets me confused, to many arms and legs lol
