Check out your girlfriend or wife’s little toe if you think you’ve nearly caught her red-handed with a love rival.
In most women, the little toe turns red after sex and stays red for up to twenty minutes.
Other post-coital physical evidence to watch out for is glowering cheeks, a red rash on her chest or neck, slightly swollen lips and rapid eye blinking.
And of course there is the obvious one…a penis breath.
