Matthew 19:4-6
4 “Haven’t you read,” he replied, “that at the beginning the Creator ‘made them male and female,’[a] 5 and said, ‘For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh’ 6 So they are no longer two, but one flesh. Therefore what God has joined together, let no one separate.”
Jesus was addressing divorce and in doing so He was clearly promoting one man, one woman marriage. When the Pharisees asked why Moses allowed divorce, this was Jesus' reply:
Matthew 19:8-9
8 Jesus replied, “Moses permitted you to divorce your wives because your hearts were hard. But it was not this way from the beginning. 9 I tell you that anyone who divorces his wife, except for sexual immorality, and marries another woman commits adultery.”
This was the disciples reaction:
Matthew 19:10
10 The disciples said to him, “If this is the situation between a husband and wife, it is better not to marry.”
^^^ This is key right here because the disciples were saying that men shouldn't marry then.
Jesus responds:
Matthew 19:11-12
11 Jesus replied, “Not everyone can accept this word, but only those to whom it has been given. 12 For there are eunuchs who were born that way, and there are eunuchs who have been made eunuchs by others—and there are those who choose to live like eunuchs for the sake of the kingdom of heaven. The one who can accept this should accept it.”
In other words, the men who do not marry and accept that marriage is not in their cards fall into these categories: they were born with no libido, and then some made to have no libido. And then there are men who do not marry because they want to live for the kingdom of god.
Clearly, it can be concluded that men who fall outside of these categories were designed to take a wife and should take a wife. To which sex they're attracted to is of no relevance.
It is in God's design that marriage is to be of one man and one woman.
