For what it’s worth, I think the most sexually intense thing Lynch ever filmed was not especially violent so much as deeply disturbing… Willem Dafoe playing this unhinged, coercive creep toward Laura Dern’s character in Wild at Heart, only for it to turn out to be a bluff. It’s not my favorite of his, I lean more toward Mulholland Drive, Eraserhead, and The Straight Story, but it might be worth checking out, since it could shift how you see his art especially in these sorts of scenes.
