I gave up deodorant and antiperspirent ages ago. Also, I gave up shaving my armpits. I do shower every day, I am generally pretty hygenic, although I do sometimes smell a bit sweaty. I prefer that smell to perfume or deodorant, generally.
I use scented moisturiser pretty often, but not on my boobs while breastfeeding.
I hadn't realised everyone shaved their pits and used products there. Although thinking about it, I'm sure most of all of my friends do.
