Kali-yuga is so fallen. If a young man sees another young man, he's enjoying with another young girl, then naturally his lusty desires increases. So these things are forbidden therefore. Still in some places it is forbidden that you cannot . . . India, this is strictly forbidden. There is no such thing in the public street a young man can embrace or kiss. No. That is not possible. Then it will be criminal. Neither a young boy can dare to speak with another young man (girl) on the street. Still it is criminal. She'll again immediately protest that it is incivility.
So the whole civilization is how to restrict this sex desire. Because . . . why restriction? Because the sex desire and sex life will keep him within this material world in different bodies, either as human being or as animal or as bird or as insect—so long there will be this sex desire. To become free, to become liberated means to become liberated from sex desire. That's all. This is the basic principle. Not that this tantra-yoga, how to increase sex desires. This is not civilization. Civilization is how to cut down sex desire and ultimately become free, paramahaṁsa. That is civilization according to Vedic culture. Therefore the training from the very beginning, brahmacārī. Brahmacārī is instructed in such a way that he'll remain brahmacārī throughout the whole life. A brahmacārī is open to accept either a gṛhastha āśrama or vānaprastha āśrama or sannyāsa āśrama. But the guru advises, "Better remain all through brahmacārī. No botheration." So he's trained properly, but still if he has desire, then he's allowed to become a gṛhastha. That is also for a limited time. The whole plan is how to stop, because as soon as here, that Ajāmila, he was not properly married, he became the husband of a prostitute. But there are ten children, but he's entangled with the family, with children, and now he's engaged bhuñjānaḥ prapiban khādan bālakaṁ sneha-yantritaḥ, one after another. First of all sex desire, puṁsaḥ striyā mithunī-bhāvam etam (SB 5.5.8).
This world, what is this world, material world? The material means sex desire. That's all. The woman is hunting after man, and the man is hunting after woman. Either in human society or bird society or beast society or dog society or cat society, the principle is sex. And the human society means to understand it, that what is the basic principle of material life. If we understand it is sex, therefore we have to cut down the sex desire gradually by becoming brahmacārī, gṛhastha, vānaprastha, sannyāsa. This is the process.
