Onan's sin was not fulfilling his duty to raise up a son for his brother. The "spilling of seed" was merely the method by which he committed his sin.
For a married couple today, there is no such responsibility, and therefore no prohibition.
I have already addressed your attempt to correct me merely by the use of a different translation. It's not going to fly. I'm not interested in repeating myself.
Ephesians 4:30 doesn't say that the Holy Spirit will lead us into "all the truth necessary to holy living"; it says He will lead us into all truth.
Why do you keep misrepresenting God's holy word?
It is impossible to lust over your own wife, just as it is impossible to steal what already belongs to you.
As long as your wife is aware of and truly accepting of your actions, it's nobody else's business.

"Even the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you."
Even a sparrow does not fall to the ground outside of the will of God.
Stop arguing about molehills and start dealing with the mountain of unbelief in your heart.
