Is it normal not to use a bed sheet?

I was just wondering. It's not like I'm not clean or anything, I shower before bed and clean my feet and such, I just don't like using a bed sheet. I move and kick around in my sleep, and I used to always get woken up because it would get tangled in my feet. So about two years back I just stopped using a bed sheet. Is it normal that I don't use a bed sheet
