I rely on other people to tell me if I smell bad. I try to make sure that my close friends know I have no sense of smell, in the hope that if I have an odour problem they'll realise I need to be told about it, but I am essentially at their mercy.

I measure the dose of deodorant by its antiperspirant qualities: I use it when I feel sweaty, and I use the minimum amount needed to stop me feeling sweaty. If this is serious overapplication or underapplication, I would hope somebody would have told me so by now, and I urge them to do so if they've previously been politely keeping quiet about it!

Last time I chose a deodorant, I was going out with lark_ascending, so I took her shopping and got her to choose one she liked.

I don't use any other scented toiletries (shampoo, shower gel, soap etc), because my last GP suspected them of irritating my sensitive skin.
