Should I delete porn?

I have a private tumblr page where I repost porn that I see on tumblr that I like. Should I delete this tumblr? Or just take a break from it?

From what I have seen on your brain on porn, internet porn is not good at all and should be avoided. So I was thinking about deleting. It is hard though cause of all the sexiness there.
Tumblr is hard because even though it is great feeling, it is a never ending dopamine spiral of novelty and the next girl. I guess I should delete it. Crap.

I don’t have a moral obligation to porn but if it is jacking my brain up, I guess it is evil.
