Did men really share their wives with others in communist countries?

I'm going to quote the Communist Manifesto on this - later Communist thought on this topic didn't deviate too far from Marx:

But you Communists would introduce community of women, screams the bourgeoisie in chorus.

The bourgeois sees his wife a mere instrument of production. He hears that the instruments of production are to be exploited in common, and, naturally, can come to no other conclusion that the lot of being common to all will likewise fall to the women.

He has not even a suspicion that the real point aimed at is to do away with the status of women as mere instruments of production.
