Virgos are cheaters and the fact that they are intelligent they are difficult to catch them in the act. Though its easy to catch a male Virgo cheating because they can become sloppy. Females are difficult to catch in the act because they tend to be loyal to one particular partner.
Virgos flirt subtly though they require you to be direct. The moment you flirt with them direct they go blank or simply dissapear on you. Only to comeback after they have processed your flirtatious words. They are so funny that they get caught in this tree trunking game.
