Firstly, I just wanted to stress that I have absolutely no problem with girls who DO wear make-up; it's just not for me personally. :)
Basically, like the question says, I almost never wear make-up unless it's a formal occasion. I would consider myself to be pretty average in terms of attractiveness, though I'm lucky enough to have clear skin more often than not.
I do take care of my appearance by moisturizing daily and taking care of my hair, but I'm just not comfortable with make-up (I always either worry about rubbing it off, or feel awkward with it because I'm so used to seeing myself without).
Guys: is this a turn-off? And just to re-iterate, I don't mean to cause any offense: I love make-up on others, but just prefer to avoid it on myself. :)
As a matter of fact I know a lot of girls who look great without makeup. It's actually pretty pointless a lot of the time. So many girls who wear makeup, and they look great as is, then paint their faces too much, or equally pointless, they apply almost no makeup at all, in a way that I can barely tell a difference. Still, I don't have a real problem with makeup, I just find it pointless.
So no. A girl who has no makeup is not a turnoff. Not in the least.
personally I think its pretty amazing stuff. it can make even the most hurt girls look hot. and generally I do like a small bit of make-up on girls. but hey, if you're hot enough to always pull off the no make-up look, that's great, do what you do.
