Different versions?

I just watched this on Netflix streaming and had to wonder about something. I first saw this film on HBO around 1980. Other posters here refer to it as a boob and butt fest. Yes it WAS that!
I remember the HBO version being a bush fest as well, two scenes in particular: when the kids were peeping at Fay through the hole in the wall (near the beginning, when TT got "caught") and near the end when Duke and Fay found Corky in bed asleep with TT. I remember both scenes showing full frontal female nudity. I wonder if different scenes were filmed, and the toned down versions inserted for Netflix, or even for subsequent releases?
Does anyone else remember seeing the original, as I remember?
