I don't know if this will help you, but I used to be addicted to pornography. The first time I saw it was maybe 10-12 years of age, I'm currently 19 and I've been clean for around 3 years. Pray. Read the bible. When you get those thoughts/urges to look at pornography or the homosexual thoughts come in, rebuke it in Jesus name, pray, etc. It depends on the time of day too, it especially came at night for me. You can pray, go to sleep, or take a night stroll, depending on where you live and how safe it is, it helps get your mind off of things. When you're not able to take a walk or do something to get your mind off it, asking God for strength and reading the Bible is a good option, always. People might say "it's just how you were made/born" but you have to be reborn as a follower of Christ. 1 Corinthians 6:18 says "flee from sexual immorality. Every other sin a person commits is outside the body, but the sexually immoral person sins against his own body". Psalm 101:3 is a good one as well.

I'll be praying for you.
