I agree. If you have armpit odor...I'm not gonna date you but I can work in the same office w/ you.
But if it's that smell of a grown man who hasn't washed his butt crack or pants in many, many days and he hasn't brushed his teeth or rinsed his other orifices AND he smokes, I will literally vomit.
Some ppl (male or female) cannot reach their crotch/butt region, no matter how often they rinse their body in the shower, and it aways smells.
IDK exactly what a period smell is but I have smelled some nasty crotch/butt on women and it is truly sickening.
But there is also this odd combination of cigarettes and alcohol, like you sleep on the floor of a bar. I am no tee-totaller and I smoked for many years. But sometimes ppl just emit this very noxious smell combining those two things, and it willl have me bent over the toilet in a minute!
