I might call HDs more 'inner' focused and LDs more 'outer' focused in terms of what influences a person's sex drive... the 'state' of the R seems to have very little influence on the SD of people we call HD.
Yeah, it's amazing how the sex drive of the people formerly-known-as-LD improves when the 'state' of the relationship becomes one in which the spouse formerly-known-as-HD is someone who no longer lives with you and suddenly looks really hot when you run into her in the grocery store or hear about her new BF.
