I assume that you refer to Eph 5:21. But this is a generalized command within the Christian church, Paul makes a point of “hupotassoe” when speaking to the wife (and a point of agapao when talking to the husband) indicating distinction between the two.

And on the possible meanings of “hupotassoe,” it should be pointed out that this is the word used in Luke 10 to describe the subjection of devils to the commands of the apostles. I think this could hardly be couched as a friendly exchange of suggestions.
