Krishna Consciousness is a Society. Society means men, women, children, families, etc. Lord Caitanya Mahaprabhu married twice. Nityananda, Adwaita Acharya, Srinivas, Gadadhar, they are all married men. Srila Prabhupad was a family man. Krishna married 16,108 times. Married life is allowed, it is a part of Krishna Consciousness

The purpose of marriage is for husband and wife to assist one another in their service and progress on the path of love for Krishna.  As we will read, Srila Prabhupad encouraged and wanted that all women be married. Especially every young woman must be married. Srila Prabhupad encouraged that brahmacari should remain life-long brahmacari, if possible. At least it is advised to wait as long as they can. Brahmacari is time for self-control, austerity. To build up strong character. Srila Prabhupad instructed, and Manu states in the Manu Samhita, that a boy should put off marriage up until the point when his service or duties become hindered due to mental agitation. Then he can marry. But, for girls, Prabhupad taught that prior to puberty they should be married. And girl should be given a child as soon as she is able.
