Do you notice any stimulus or frustration that happens around the desire? Like a patch of skin that won't stop itching, or an emotional trigger - maybe something agitating you at the time that seems unrelated?

I was feeling very anxious about a couple of things. Maybe it's related to my anxiety?
That's a distinct possibility! I know you said you don't have OCD but you don't really have to have that specifically; overgrooming is a feature of anxiety-related disorders like OCD because it's related to anxiety, so it can show up in less-severe forms as a disordered behaviour even without you suffering the full pathology. Worth keeping an eye out next time you feel it coming on, see if you notice anything else about it.
Only when i'm feeing particularly slimy or sweaty. Asd here too, the facial hair is driving me up the wall tactile-wise though!
Btw, unless you're sweating up a storm all the time, you don't have to bathe every single day - modern lifestyles simply don't stress our bodies enough to stink up in that short a period.
I get that feeling after sex with your mom.
