It only matters what somone else 'deems' if you chose to let it matter.

These misconceptions are the result of false teachers who add lies to the Gospel

Quite, and there's a big large pile of them in the basement of St Peter's, too.

It is true that The Bible instructs us not to seek a wife:

Are you bound to a wife? Do not seek to be loosed. Are you loosed from a wife? Do not seek a wife. (1 Corinthians 7:27)

But this does not mean that marriage (and therefore sex) is forbidden:

But I say to the unmarried and to the widows: It is good for them if they remain even as I am; but if they cannot exercise self-control, let them marry. For it is better to marry than to burn with passion. (1 Corinthians 7:6-9)

"the christian utopian view reinterpreted sex to deny the pleasure but admit the procreation."

This would be to deny The Bible, which says:

Let your fountain be blessed, and rejoice with the wife of your youth. As a loving deer and a graceful doe, let her breasts satisfy you at all times; and always be enraptured with her love. (Proverbs 5:18-19)

Not to say that your observations are incorrect; the overwhelming majority of self-described "Christians" follow the broad path to destruction:

Enter by the narrow gate; for wide is the gate and broad is the way that leads to destruction, and there are many who go in by it. Because narrow is the gate and difficult is the way which leads to life, and there are few who find it. (Matthew 7:13-14)

These misconceptions are the result of false teachers who add lies to the Gospel:

But there were also false prophets among the people, even as there will be false teachers among you, who will secretly bring in destructive heresies, even denying the Lord who bought them, and bring on themselves swift destruction. (2 Peter 2:1)
