That can be a symptom of neurodiversity, both ADHD and Autism (or AuDHD) - disruption to activities, transitions, sensory input, etc.
Acknowledging it is a 'thing' for you can make it easier to do because once you've accepted that it is probably better to shower more, whether for actual cleanliness or skin health itself, making a routine, social expectations, that once you're in the water it's nice, whatever, it can make it less of a bind to actually do it.
After a while, it becomes a more normal part of your day or self care and easier again, as feeling clean, being under the water, whatever scent or texture of soap/shampoo, removing dead skin and not providing a good home for infections, bacterial and fungal, is then your feeling 'right', or it could prime you for the most restful sleep/best start to the day, whichever feels right for you.
It's stretching out the timescale and they are very specific examples, but if, for example, your dog were to stand on your foot and scratch it with its claws, it might be fine - but without a regular routine of showering, what could happen is that you don't think anything of it and a serious infection takes hold.
The following are also possible scenarios that could happen without regular showering;
a) You could suddenly have an incredibly painful spot where an item of clothing has rubbed but it's got fungal colonisation and it splits and won't heal - or maybe turns into an ulcer.
b) Your scalp is suddenly burning because it's spread and hair starts coming out because your scalp is red raw and weeping.
c) Depending upon your age and lifestyle, it is common for people to develop T2 Diabetes - daily foot and skin care is absolutely vital and if you aren't already in a routine of looking after yourself, sometimes the first signs are when something's already gone very wrong, instead of 'hmm, my foot feels funny' or 'that blister's not healing/I didn't even know I had one, it's quite deep/am I supposed to see that white-yellow stuff at the bottom of it?'.
Or with regular showers;
a) You realise that actually, having a shower in the morning makes you feel less achy or sore when you hadn't noticed before that you do have some pain and discomfort in the morning.
b) You find you sleep better or wake up feeling better or when you're upset, angry, irritable or just plain fidgety and uncomfortable, it makes you feel calmer and patient with yourself.
c) Doing this thing for your benefit gives you 'permission' to do other things to look after yourself. It's not a faff to put yourself first then, meaning you might eat healthier, say no to things you really don't want to do, make choices that are right for you physically and emotionally.
These are just ideas and examples, not a 'Ewwwwwwwwwwww, you're disgusting and lazy'. It's very common for neurodiverse people in particular to find self care difficult and all too much of a hassle - but it can also apply to anybody neurotypical as well, especially if they're finding things difficult due to external circumstances causing them stress.
And yes, whilst you may not smell bad now, it's very easy to not really notice a crossover into less socially acceptable hygiene levels. And people don't like to say anything (well, outside MN, at any rate) until it's really becoming a problem.
Maybe just have a think about things and whether it could be better to increase the frequency to see if over time, it becomes more pleasurable/at least more tolerable or has other benefits. Because doing things that keep you healthy, well and comfortable are not a faff, they're what you should be allowing yourself to do as your right.
