I was wondering what was the origin of the different types of sexual acts one can commit. I mean, the normal is regular sex, then we got anal sex, and the whole oral thing.... And I mean, would our primitive ancestors would have done anal sex or/and oral sex? And if they did not do such acts, then where did they originated from? I mean, if I would have not heard about anal sex and oral sex, I would have probably never thought them possible...
You know what I am saying?
