Body odor is never an issue for me (knock on wood!). I do not wear deodorant. I did at some point in my very early teens because I thought it was the right thing to do. I only did it for a couple of months and it simply annoyed me. It is just another annoying addition to my long morning ritual. If I forget and apply it after I have already put my top on, it leaves funny white marks at odd places. It takes me a while to wash it off in the shower. My time in the water is long enough as it is, spending ten minutes on my armpits is just too much.
After a while, it occurred to me, I was fine before I started using deodorant. No matter how much I sweat, my smell never changed, I still smell like – skin. I know this because when I went off the deodorant, I would go to the washroom whenever I feel my armpits are damp and sniff. Immaculate. I went as far as asking my mum to do the sniffing for me at some point and my mother does not lie.
