Is it normal for mothers to walk around naked?

Growing up my mother, my sister and I all did. None of my brothers or my father ever did. I used to feel sorry for guys having to stay dressed. When we, kids, started bringing friends home to visit mom stopped being naked at home until nearing bed time. I stopped just before I got my period. After I saw Porky's, the movie, I got rid of my blinds and curtains. When I first moved in with my man, I basically was nude all the time. I'm not as daring as my mom is. My kids don't see me naked.
