casual sex?

People can do what they want, and what might work for some people will not work for others. Me, personally, I could never have just casual sex with someone, my casual sex is called me masturbating... And is "casual sex" a type of relationship? I thought it was just people having sex together when they want, no "set relationship" ah, man, so many rules... Pfft, anyways I don't have sex, sex is for lamers...
