No such requirement exists. In fact, the following passages show that this argument is dead wrong.
Matthew 19:10-12
"10 His disciples say unto him: If the case of a man with his wife be so, it is not expedient to marry.11 Who said to them: All men take not this word, but they to whom it is given. 12 For there are eunuchs, who were born so from their mother’s womb: and there are eunuchs, who were made so by men: and there are eunuchs, who have made themselves eunuchs for the kingdom of heaven. He that can take, let him take it. "
Ist Corinthians 7:6-9
“6 But I speak this by indulgence, not by commandment. 7 For I would that all men were even as myself: but every one hath his proper gift from God; one after this manner, and another after that. 8 But I say to the unmarried, and to the widows: It is good for them if they so continue, even as I. 9 But if they do not contain themselves, let them marry. For it is better to marry than to be burnt.”***
***Revelation 14:1-5
******1: Then I looked, and lo, on Mount Zion stood the Lamb, and with him a hundred and forty-four thousand who had his name and his Father’s name written on their foreheads.
2: And I heard a voice from heaven like the sound of many waters and like the sound of loud thunder; the voice I heard was like the sound of harpers playing on their harps,
3: and they sing a new song before the throne and before the four living creatures and before the elders. No one could learn that song except the hundred and forty-four thousand who had been redeemed from the earth.
4: It is these who have not defiled themselves with women, for they are chaste; it is these who follow the Lamb wherever he goes; these have been redeemed from mankind as first fruits for God and the Lamb,
5: and in their mouth no lie was found, for they are spotless. ***
