Late 70 early 80’s, I think on PBS, maybe not.  Anyway movie or show about young couple, maybe dropped out of high school or just graduated.  Scene I remember as follows.

Girl and guy in bedroom of apartment.  She takes off her clothes and stands spread Eagle in front of him.   He responds ” your body,  it’s beautiful”  they then proceed into bed I guess

Second scene same apartment she’s on the balcony in some sort of nightgown, struggling over some issue, maybe she’s pregnant etc.

This was some sort of moral lesson/coming of age program, but I think that there was nudity and certainly controversial subject matter for the time.

That’s all I can remember
