Prabhupāda: The Vedic principle is that one should avoid sex life altogether. The whole Vedic principle is to get liberation from this material bondage. And there are different attachments for this material enjoyment, out of which sex life is the source of topmost enjoyment. The Bhāgavata says that this material world... Puṁsaḥ striyā mithunī-bhāvam etam (SB 5.5.8). Means that a man is attached to woman and woman is attached to man. Not only human society, in animal society also. That attachment is the basic principle of material life. So, a woman is hankering or seeking after the association of a man, and a man is hankering or seeking the association of a woman. Just like we see the, all the fictions, novels, dramas, this cinema, or even ordinary advertisement, simply they depict the attachment between man and woman. Even in tailor's shop you'll find on the window some woman, some man. (break) So this attachment is already there.
