I haven't heard from you long time and i thought you're on a binge. Fortunately you're fighting. the event with your daughter was God's rescue. Many years ago before my marriage I had a similar event when I wanted to make sex with a married woman and the last obstacle was her little daughter who came crying in the last moment into the room ( it was night ). the woman was my neighbour and the results of the affair could have been horrible.
In my opinion the fact that you have the opportunity to have enough sex with your wife and despite of this you're more interested in porn can be the sign of demon's activity. Quit all connection with occult ( Silva meditation), go to confession and pray sufficient.
Most glorious Prince of the Heavenly Armies, Saint Michael the Archangel, defend us in "our battle against principalities and powers, against the rulers of this world of darkness, against the spirits of wickedness in the high places." (Ephes., VI, 12) Come to the assistance of men whom God has created to their image and likeness and whom Jesus has redeemed at a great price from the tyranny of the devil. Holy Church venerates thee as her guardian and protector; to thee, the Lord has entrusted the souls of the redeemed to be led into heaven. Pray therefore that the God of Peace allows men of faith to expel Satan, that he may no longer retain men captive and do injury to the Church. Offer our prayers to the Most High, that without delay they may draw His mercy down upon us; take hold of "the dragon, the old serpent, which is the devil and Satan," bind him and cast him into the bottomless pit "so that he may no longer seduce the nations." (Apoc., XX, 2)
Thanx for your hints to me.
