A different case

I am a 19 year old boy from India. I have been masturbating since when I was 13 years old. For the past 3 or 4 years I have approximately masturbated twice everyday. Recently I tried to abstain from it. But after 6 days, I had a strong urge to jerk off, so I broke my streak. Now the thing is I don't like porn. I don't masturbate to porn, rather I watch sex scenes of actresses from movies. I just love to see celebrities nude. I want to ask whether this is normal ? Is it doing any harm to me? Is there a difference in watching porn and watching what I see? Do both of these things affect our brain in the same way? I know that I am addicted to masturbation, but is it fine if it is not done to pornography? Also I have become a lot lazier and lathargic lately. I don't know if it is because of excessive masturbation or some other reason.
