Hi... I also suffer from Body Odor (supposedly, I can't smell it myself.) and, like you, my family (even some members of my immediate family, who aren't living with me) insists that it doesn't exist. So, at least for me, it can't just be that they're used to it, unless they got desensitised to it when they were growing up with me (Although, I don't think I had the odor then.). It also seems that everyone (outside of my family) who I outright ask (such as my doctor) says that they can't smell me. It's very frustrating, because 90% of people gives me every indication (short of actually coming right out and telling me that I stink) that I do have BO!
