This poll is in effect a double poll. If it was just about the acceptance of or the attitude towards thongs, it should have stated partner instead of wife or husband. Partner is supposed to be a neutral term.
If you want to see if male partners or female partners have different acceptances or attitudes, you could adapt the poll accordingly.
If you make a poll you should analyze what data you want to see and formulate your questions accordingly. With wrongly formulated questions you might contaminate the results. Making polls is a scientific business.
My wife likes thongs on me. My female partner for 15 years ,of Italian descent, hated skimpy undergear on men.
