Murderbot Diaries is SFF with an asexual non-binary security cyborg who loves watching terrible SF TV and it's one of my fav series ever.
Loveless by Alice Oseman is about an aro-ace person coming to terms with their identity at college. Other characters have sex but I don't believe the POV character ever witnesses any sexytimes.
Gosh I've definitely read more but that's what I can come up with atm!
