My partner(M38) and I(F30) have been exploring the lifestyle and we've established some boundaries that work for us.

For me, kissing and oral are fine for him and another woman, but I draw the line at PIV. On the other hand, my partner is open to pretty much everything for me, and enjoys watching me with another man including PIV, but they have a rule that men must always wear a condom if we get to that point. We’re aligned on these boundaries for each other and they’ve worked well in our first few experiences.

I'm curious-are these boundaries common in the lifestyle? We try to over communicate with anyone we interact with, but just curious if this is a common dynamic for other couples.
