Most Helpful Guy
Many animals have bits that flush with blood and become redder when they are ready to mate, so it makes sense that 'redness' can be a turn on.
However, IMHO, when you redden lips using makeup, it's fake, and doesn't turn me on. I'm much more attracted by a natural redness, (e. g. blushing and swollen/parted lips) than fake colours from cosmetics. If you want to redden your lips, just give them a bit of a massage!
From my point of view, more makeup = higher maintenance - something to avoid. Therefore, the less makeup a girl is wearing, the more attractive she is to me. It tells me she has a strong mind i. e. she hasn't been conditioned by society to believe that she isn't beautiful without it, and/or she an environmentalist, ie. she has an understanding of how the cosmetic industry is such a drain on finite planetary resources and is such a creator of trash and pollution that she'd rather vote with her feet and not use them.1
