I take at least one shower a day. It used to be five but my doctor told me to calm down and take short cool showers.
I can smell myself on random occasions, I was doing a leafy green fast last week and when I was in bed I could smell this weird odor emanating from my sheets.
I dont know, if I could smell myself constantly I would probably go nuts. But if I spray myself with perfume or body wash I can smell myself more.
