To get my kid to wear deodorant

So hear me out: my kid is going through puberty right now, and we keep trying different ways to help him remember to use deodorant. I’ve bought it for him, let him pick out his own scent, and even left it right on the sink so it’s directly in front of him when he gets out of the shower. Yet somehow, he still forgets every single time. Since he plays sports and spends a ton of time outdoors, you’d think applying it would be a straightforward task — does he really not smell himself?
