Most societies I am aware of still have males and females. There are various exceptions - e.g. various groups that perceived to be "outside" of the binary structure - but these would be still defined groups and there still would be labels. Could you give examples - more than one - of cultures that really perceived gender as a gradient?
For sexuality it is more complex since not all cultures have western fixation on sexuality and thus the question of who rubs which part of their body on which part of whose other body may not be as prominent as in our culture. I.e. they may have a concept of "gay" but it would be as big part of one's identity as "coffee drinker" or "likes to wear jeans" is in ours.
