Do u know what "sex" means?
It means "The sexual urge or instinct as it manifests itself in
behavior." and "sexually motivated phenomena or behavior."
BJ is sex. If u think BJ is not "real sex" , u r trying to find
excuse to lie to urself. U r like Bill Clinton. He made an excuse
that what he and Monica did was not really considered sex, BUT
actually it was.
BJ, phone sex, cyber sex, all considered sex.
And.....that's all....whether u may do it with ur sis, u should
know urself.
