In fact they have, humans faces turn a bit pinkish or flushed when they are
interested in sex. If you make eye contact with a woman who finds you
atractive, and you allow her to see that you think as much, then you can bet
that your face has turned a bit pink.
If she like you back you might see her face and perhaps neck turn a bit
pinkish, but you don't usualy becouse they already have it painted that
color. I think they call it rughe. Like, it's all one bit rughe.
