If you were to meet a man and end up going home with him only to find out he was wearing a thong. What would your reaction be? Would it be a turn on or off?
If he was slim, fit with a sexy (not hairy) bum it might look good but I wouldn't be turned on or off by it.
My only concern would be why he was still wearing it!
Men in thongs dont do it for me, Id just have him take it off lol
