YourTango Quickies: New Factoids On Cheating, Orgasms & Divorce

This week YourTango launches a new feature: YourTango Quickies. Appearing Tuesdays at 5 pm, this post will be a round-up of sexy, surprising and significant sex, dating and marriage facts from the past week. Use these facts to impress your date, wow your husband or wife, spark conversation among your friends or just to scratch your head about the weirdness of life and love.

Cheating runs in families. Men are more likely to cheat if they grow up with an unfaithful father. So Arnold Schwarzenegger's son is even worse off than we thought... What's weird about this study is that the daughters of adulterous dads aren't more likely to step out on their men. The researchers didn't give very good explanations for this. Monkey see, monkey do was the basic explanation—boys see their fathers cheating and assume that it's OK. Girls take their relationship cues from their moms.

The site's founder is the author of a book called Seeking Arrangement: The Definitive Guide to Sugar Daddy and Mutually Beneficial Relationships.
