Help finding a late 70's/early 80's movie

[Aeryn]

Please help me make my boyfriend happy! He was reminiscing about a porn movie in the very late 70's or early 80's. It was basically a story of the evolution of sexual behavior. It started off with a caveman-like scene and ended with a sophisticated scene of a brunette woman giving oral. For some reason he thinks the title may have been "Once Upon A Time," but I can't find it on any search engine using that title.

Don't have actor/actress names, so sorry -- it was just too long ago.

THANK YOU for any help anyone can give!

Darn, i remember one like that. There was a caveman having sex with a woman, then another caveman chased him off, and he had sex with her. but it went on, i think that's the one you are talking about

It might be ""Cavewomen"" (1979)

Thank you, but that wasn't it. I really hoped it was. Ah, well.

Thanks for trying! I really want to find this for him but without an actor or actress name or definite year, I think it's probably impossible.
