Oh I definitely experience this. It is so confusing, but i do believe that u are right all those factors contribute to our issue. So frustrating and embarassing. I share an office witha young guy, 25 yrs old. For 8hrs he is totally locked up with me in this small space. He NEVER makes a comment, gesture or anything like that. Neither does my manager. I was brave enough to ask him if he smells the odor and he said "No". I wouldnt take "NO" for an answer so I begggged him to tell me the truth. I asked him to walk out of the room and re-enter to see if he can smell it. He walked out of the room for a couple of minutes then said all he smelled was my perfume when he came back in. Still didnt believe him so I asked him to do it again and then he politely said he only smelt my perfume and something a "little off". LOL..I felt sooo bad to put himn through that.
