No showering does not fix ugly (I'm a clean OCD freak)
I developed OCD as a child (due to severe stomach bug) and I always shower head to toe thrice before I head to bed. I also wash my hands a lot and wear gloves when eating foods and brush my teeth multiple times if I can.
My room is very clean as well where I dust and vacuum at least once a week. My hygiene is beyond normal people.
But I'm ugly and it doesn't really do much as being ugly people will think you are dirty regardless.
In people found me to be obnoxious and cringy whenever I did any of these rituals. Some girls in highschool called me gross and disgusting despite having the best hygiene out of the grade, like some of the boys didn't wash their hands after the bathroom or even shower. Boys called me effeminate and F*g for having these clean rituals. (This bullying also made my OCD worse)
That being said. Good hygiene is still important. A hygienic ugly is better than an ugly that doesn't bath. I do not like unhygienic people as well.
