I am indifferent. To me the lewd games take one of two varieties. A story, or fap material.
For a story, their face is just a characters face. For fap material, it's basically just like a male porn actor. They're a part of the scene but not the part I care about.
I will say, that I am amused when I notice the lengths developers go to to hide the male protagonists face. It's kinda funny to see a faceless male body in anime style, or comically placed obstructions in a scene that has to be built entirely detail by detail in exactly the place the author wants stuff.
is nice, its normally to put the focus on the other part. i think its better done when prota's face just doesn't show (because of hair or something) than to full un-personalize it
as long as the face mostly fits the character it's fine, but is dev want to avoid showing it, then it usually doesn't bother me, the WVM black box being the exception
