research coupled with procrastination is physically addictive in a fairly severe degree. Think about it. If addiction is the idea of repetitive behavior that brings immediate physical pleasure, and an climax is one of the most intense pleasures you can feel (evolutionarily, it makes perfect sense since the entire point of evolution is to select for individuals who have the highest instinct and capability to breed), and if you look at pron to achieve an climax, of course you're going to become physically addicted to research.
Now, personal opinion here. I think that this'll forget you up later in life, degrade your respect for women, degrade love in general, and generally lead to a worse disposition in life than if you didn't. However I wouldn't go so far as to say it'd cause you act in a negative way, rather just cause you to feel generally more negative than if you didn't masturbate.
