Is it normal to not want to wear underwear?
Yep.Totally normal
Yes. Plenty of people find underwear uncomfortable or simply prefer going without it.
It’s a normal personal preference. Underwear can feel restrictive, bunch up, or just be one more layer you don’t want. Some people wear it every day; others skip it whenever they feel like it.
Just consider what you’re wearing over it and what you’ll be doing—seams, sweat, and friction can make certain outfits or activities less comfortable without underwear. Otherwise, if you feel comfortable and keep your clothes clean, it’s your call.
