"The Law of God is inherent.... and inerrant."

If I understand you (correct me if I'm wrong), you're referring to Natural Law: the law that derives from human nature, having certain God-created instincts which constitute an kind of "Law of the heart."

If this is what you're speaking of, then yes; but one has to distinguish between this Law, and all the other inward things that might rival it or distort it, such as inordinate appetites, inclinations, and drives.

Even a natural philosopher, to understand Natural Law, has to look broadly to compass all of human nature, across cultures, continents, and centuries... not merely his own individual tendencies

Keep in mind that our natures, inherited from Adam, were wounded by his sin; our natures are no longer inherently good as they were when God first created Man in His image and likeness. Because of these inherited tendences, our inner self can be bleared, smeared, distorted, diseased.

Jeremiah 17:9
The heart is deceitful above all things and desperately sick. Who can understand it?

Deuteronomy 12:8
You shall not at all do as we are doing here today—every man doing whatever is right in his own eyes.

Proverbs 3:5
Trust in the LORD with all your heart and lean not on your own understanding.

That's why people who study Natural Law can't just go with whatever seems right to them.

Proverbs 21:2
Every way of a man is right in his own eyes: but the LORD pondereth the hearts.

Romans 10:14-15
How, then, can they call on the one they have not believed in? And how can they believe in the one of whom they have not heard? And how can they hear without someone preaching to them? And how can they preach unless they are sent?

The heart of man itself asks:

Psalm 119:34 Give me understanding, and I will keep your law and obey it with all my heart.

And God answers:

Jeremiah 3:15
Then I will give you shepherds after my own heart, who will lead you with knowledge and understanding.

We have the advantage of God's Law revealed explicitly to us: we have our shepherds who guide us in knowledge and understanding. That's why we refer to the obligation of conscience to think with the mind of the Church.

Jer 4:1 "If you will return, O Israel," declares the LORD, "Then you should return to Me. And if you will put away your detested things from My presence, And will not waver,
Jer 4:2 And you will swear, 'As the LORD lives,' In truth, in justice and in righteousness; Then the nations will bless themselves in Him, And in Him they will glory."
Jer 4:3 For thus says the LORD to the men of Judah and to Jerusalem, "Break up your fallow ground, And do not sow among thorns.
Jer 4:4 "Circumcise yourselves to the LORD And remove the foreskins of your heart, Men of Judah and inhabitants of Jerusalem, Or else My wrath will go forth like fire And burn with none to quench it, Because of the evil of your deeds."

Eze 22:26 Her priests have violated my law, and have profaned mine holy things: they have put no difference between the holy and profane, neither have they showed difference between the unclean and the clean, and have hid their eyes from my sabbaths, and I am profaned among them.

We have the advantage of God's Law revealed explicitly to us: we have our shepherds who guide us in knowledge and understanding. That's why we refer to the obligation of conscience to think with the mind of the Church.

What do you do when the shepherds are themselves sexually devient and profaners of the Law of God?
