Is This even possible for me?

Of course it's possible! Priests and monks have been doing it for centuries.

And the amount of porn we can get, easily and anonymously, is really super new. Even back in the early 90's you'd have to go buy it at a store, which is probably why fewer people did it. My point is, you probably come from a more-or-less unbroken line of dudes who barely saw any porn in their lives and had no problem with that.

People who have problems with porn addiction usually have to quit masturbation too, at least in the short-term, because the two are so linked in their brains that doing one naturally leads to the other.

No sex before marriage is your choice, but as far as I know it's not going to cause any biological problems. That's part of why we have wet dreams - it's your balls' equivalent of running an old car's engine once in a while to keep it in good shape.
