Well I believe this question is a matter of personal preference but let me answer as best I can.
Most men obviously prefer their women to have a more natural look thank the fake one that women present when they wear make up, but at the same time, men always want their women to look good so if you're going out with him to see a movie of a fancy dinner then he'll definitely expect you to look good and as such he'll expect you to put on make up.
Now if your alone with him or just going out for a quick bite to eat or maybe a walk in the park or doing anything that lets us spend quality time with you guys then we're probably not going to want you guys to out on any make up. If we just want to spend time with you then we want the real you, not you with a plastered face, you with all your imperfections.
It's not a question of if we prefer you guys without make up, it's more along the lines of *when* do we prefer you guys without makeup.
