Is Promiscuity Genetic?

Anonymous
My whole life I have grown up with half siblings on my mother's side of the family. Over the years we have been raised as siblings and not "half siblings". When I was 15 I found out that all of my siblings have different biological fathers. I was shocked and grossed out to find out that my mother would allow different men to impregnate her over and over again. Granted my mom was a beautiful woman and many men would attempt to court her but why did she allow many of them inside of her? Recently I have cheated on my current boyfriend twice and he still loves me. Sometimes I think about the reasoning behind why I decided to bed other men while seeing a guy but I can't find the reasoning. Have I been predisposed to promiscuity?
