Prayer, Religion, God are concepts that differ from person to person. They are understood individually & are personal. The concept of "God" differs from person to person; "Religion" is a "man made" thing that involves "interpretations" of life & people; "prayer" is how people talk to God.
Praying for other people is usually just a way to tell people how you think they should live. That is when personal judgement overtakes compassion & is more for the one praying, not the one being prayed for.
I find it interesting that you see a conflict between God & porn. If you believe in a loving, forgiving, & unselfish God then you know that your choices will not always be right. If you choose to participate in the world of Adult Entertainment then part of you enjoys it or gets something from it. If you think it is wrong stop participating.
Selfish behavior or God's Will? I think you are imposing your way of doing things, not God's. People are Human, human's make mistakes, bad decisions, & sometimes fail; God knows that. Each of us discerns what is right or wrong, we also falsely judge others.
Apologize & move on, it's not in your control. Accept your actions & move on. Three words helped me not long ago (I was having struggles of my own makings) move on with life: Get Over It!
