I can feel your struggle man. As long as your wife is not too controlling and aggressive about your choice for wearing thongs, like if she confiscates your thong and cuts them, then you should try casually wearing them without directly telling her I guess. If she was truly your wife, then she would accept your choice for wearing thongs as underwear. You're not pressuring nor forcing her to wear thongs. It's not like it's bad for your health like smoking and drinking excessively (sorry, no offense to people on this forum who do smoke or drink often). It's simply underwear! Thongs are the perfect kind of underwear, and it provides so many benefits. Keep thonging brother!
