Is it normal to just nut on my bed sheets and not clean up?

I think it's normal and I'm a girl. I don't think it's really sanitary, but it's not unormal. I know a lot of guys that do this. It's probably just a bad habit for you. You're relaxed after having ejaculated so you may just be too lazy at that point to clean it up. My suggestion is wash your bedding and start nutting into a napkin or rag (but than wash the rag) lol
