Oh dear, I'm going to have folk cringing......one of my many mental health issues is body dysmorphia. Basically my body disgusts me since it changed so dramatically from a nice figure to fat (I am trying to diet) , so bathing or showering is a big deal for me. Sometimes I go weeks without bathing or showering, but I do wash (this can be done without me having to see my body).
I rarely use BO basher, as I don't seem to sweat much either despite going out with my husband on dog walks etc. I know that my DH would be quick to tell me if I ponged so I don't worry too much. This is a far cry from the woman who used to bathe or shower twice daily, but then I'm not that woman anymore.
I have another friend and she showers daily but really smells bad, so much so that last week I had to tell her. I would add that in my opinion, sometimes it's not the person that smells but the clothing. Perhaps it's not laundered frequently enough, or left sitting in a machine too long after washing. Finally in some cases its not this at all but cooking smells. Go into a fish and chip shop, and I can smell that oily fishy smell on clothing for a fortnight, or cut up onions, or make a curry and the cook often smells for ages after. (Notice I don't mention smokers, I'm giving them a break as that's an illness, an addiction, and needs to be treated with sympathy).
Dare I say it but ssome really obese people seem to always have a smell that isn't nice.
