Pretty sure not knowing what your character looks like is what's intended, makes the game feel like it's talking to you in first person. . Take that away and the immersion just goes to shit
Haha i do indeed consciously hide the player characters face/hair as much as I can. You get to see his mouth in some scenes though because drawing stuff like kissing/oral sex is difficult if I've gotta hide his entire face.
usually in games like these, or doujins that focus on you as the MC, the devs/artists usually just show either from nose/mouth down to the chin portion of the face
