I think I'd much rather my wife leave me for another woman than another man. If she says "well, his dick is bigger than yours," you'd be like "goddammit, get the fuck outta here, I don't wanna hear this shit!" But if she says "she's got the wettest, hottest pussy in the world" you're like "hey, sit down, relax, talk to me...slowly." - XMASTIME

Science seems to agree with me, as a new study reveals that men are more than twice as likely to continue dating a woman if she has cheated on him with another woman than if she has cheated on him with another man.
