First things Sister I will say to you is that you are not alone in your fight. God is with you. Secondly I will say that there are other women of God dealing with this issue as well. Many times this is seen as a " man thing " but there are amany women who deal with this on a daily basis.
In answer to your question about possession I would say that most likely no. Possession is not the normal state of being even for non believers and certain is not for the Christian who belongs to Jesus. What I would say is that you are definitely being influenced by demonic spirits and oppressed by demonic spirits. The particular spirits that run with pornography are whoredoms, perversion and bondage.
How do you get free. The book of James says sumbit yourselves therefore to GOD, resist the devil and he will flee. Sumbit yourself to God. Repent, confess your sins. Then immerse yourself in the things of God. Build your relationship with HIM through prayer, reading the Word, Praise, Worship, and Fasting. You must also KILL your flesh. This is key. The flesh must be killed. It cannot be reasoned with, it cant be bargained with, it must be KILLED. God doesnt do that for us. WE must do that.
Then we must resist the devil. We must say no everytime there is a temptation. Even to the point of saying no OUT LOUD. There is no sin in being tempted. We are all tempted. The sin is when we give into the temptation.
Also key is to realize that you develop soul ties to the individuals that you watch. And those must be broken through prayer.
Kanyon also gave great advice in finding a sister in the Lord that you can make yourself accountable to. One of the enemies greatest tricks is to cause people to suffer alone in shame instead of getting the prayer, love, help and support that is needed to help them overcome.
