The other day I was with my wife in guy mode and we stopped to shop. She went into the lingerie dressing room to try on some stuff and I waited outside. Wondered around and looked at some bras etc. but noticed that women would walk by and give me a double look.
I then started to stand and watch as women approached. It was like I was a threat to safety or I might be discovering some secret weapon they knew about. They would hide the bras they were carrying so I wouldn't know what they wore.
Later we were in the men's department and a woman was buying tidy whites with no concern about it. I know that it is accepted that women buy their husband's underwear. I also have had women tell me they wished their husbands were as confortable about lingerie as I was. Little did they know it was for me.
I enjoy watching people react to the unexpected.
