i have sinned and watched porn please give me tips and please pray that the temptation goes away and for forgiveness please i will pray to i only lasted 6 days

You lasted 6 days! Great! Now forgive yourself and go longer next time. Mental discipline is very useful for sexual temptations...train yourself that every time a thought enters your mind, you will think of something else interesting. I can tell you, being a man age 54, sexual thoughts and temptations will probably be with you your whole life. These are rooted in our design. Inside the context of marriage, this a natural and enjoyable part of life God created for us. Until you're married...even afterward...you need to learn to control your urges. The less you act on the urges, the less power they have over you. The battle is in your mind.
