body odor

Are we turning into one person? Why can't he wash my scent off his body?

nana24 asks:

I've been with a man for three years, and sometimes I wonder how a man's body scent does not smell like a woman's. I told him if you are with somebody for over ten years, you start to smell like them or look like them. My question is that once you are having sex with them for a while, why is it that you can't wash their scent off you no matter how much you wash your hair and body?
