I shower daily unless I dont have anywhere to go now a days... but in the past I didn't.
When I didn't the problem was all the steps that my brain turned it into: making a point of finding clothes for after, having a clean towel, warming up the water, getting undressed, getting into the shower without getting water all over the floor, wash body, hair, awkward places, get water in my eyes and go through the point where its difficult to breathe and wash face... the stuff after was the biggest hassle: drying off body and hair so as not to make a mess in the bathroom, getting dressed and not being dissapointed with clothing choice and having to find other clothes... shaving, hair grooming, etc... cleaning up mess made in the bathroom...
I used to make it into this much bigger thing than it was...
Now a days I take my shower in the morning after I've been awake for a little bit and checked my emails and a few things... it's a part of a morning routine that includes taking care of all of that stuff as a single process... as a result I dont think of those individual steps so it's not a lot of work or a little work... its just part of the morning.
anyway... yeah I used to be a pretty smelly person... its one of the things that has had a pretty profound effect on my confidence and point of view of the world... but not much that I can do to take it back now.
I actually use the showering process as my standard for creating new daily things that need to get done to assist myself with executive dysfunction. Most dont stick, but at least they are a start.
Anyway, I am not sure if it is the same for everyone especially because I am not entirely sure that its ASD that caused me to have the issue specifically, other than part of why all those steps seemed like too much is because in the past I thought of the payoff as not significant enough to warrant the effort... still not sure if that counts.
