Ahh my fellow un-tethered... by the words of Christ ..."...All men cannot receive this saying, except them to whom it is given. For there are some eunuchs, who were so born from their mothers womb; and there are some eunuchs, who were made eunuchs by men; and there are eunuchs, who have made themselves eunuchs for the kingdom of heaven's sake. He that is able to receive it, let him receive it." Matthew 19:11-12
Though the term "eunuch" is typically synonomous with castration, i submit that the act of complete chastity would be an acceptable alternative, and render the same benefits, spiritually speaking. Though, with the male endowments intact, the temptation will be more of a burden to overcome, as the hormones and chemicals will remain.
Either way, being single and chaste does allow the person a greater freedom of devotion to serving the Lord. But of course, NOONE knows the mind, or purposes of the Lord. Rest assured, that if the Lord wanted you to be castrated, you would become so, by your will or not. So leave the temple that the Lord gave you, as He gave it to you. Dont paint it, write on it, poke holes in it or otherwise de-face it.
But never think that a person married or obligated to this world is any less capable of being used to further Christ's kingdom. The Lord uses all those who are willing to be used; we make that bargin when we accept Christ as our Savior.
So let me conclude by saying i, i think your poll needs a 4th option : As the Lord willeth.
