I watch phornography videio, and I feel horny & I masturbate daily day to day. Is it normal? Am boy

It's not abnormal. Don't worry - it's not abnormal, but it may be too much for you to feel comfortable about. That's up to you - no one else can know. If you'd prefer to do other sexual things and this gets in the way - try to find ways to gently change habits. If it troubles someone in your life that you love - try to talk about ways to keep both of you respected and satisfied. If you're okay - it's okay.
