Three billion years ago life formed on this planet. At some point similar organisms started exchanging their DNA and sexual reproduction was started. In the early warm volcanic seas that covered the earth, some proto-organism fucked another proto-organism and life has been fucking ever since.
We are the descendants of three billion years of things fucking each other. Every form of life, from man down to plant life, wants to fuck something and exchange DNA. And we are the descendants of those who fucked, not of those who controlled themselves. There's nothing wrong with fucking and there's nothing wrong with fucking a total stranger. You have a dick and it's there for one reason only, and that's to fuck with. She has a cunt and its purpose is to get fucked. That what it does. The process is to put your dick in her and deliver your semen so as to get her pregnant. That's the instinct you are born with and she's born with. Obviously, you don't really want to get her pregnant. But your body wants to feel like you're getting her pregnant, and her body wants to feel like she's getting pregnant.
Sex is best when you get down to the instinctive level. As much as we pride ourselves on being superior beings, we are just like all other life on earth and our animal instincts cause us to have to fuck. That's why you're lookin-- because your body needs it. And that's Okay. That's the way it is. I didn't make the rules.
