Fantasizing about real-life people can have its dangers too, I know it's obvious, but it's worth being said. Some people are more vulnerable to its dangers than others, it's easy for me to fantasize about someone and have a representation of them in my mind that's very different than who they are in reality. Also, sometimes the enemy tries to get racially aware people to fall in love with Jews or crypto-Jews.
About the porn thing, one thing I suggest is to try and not obsess over it or beat yourself up over it. HPS Maxine once mentioned the quote "the tightest grip is with an open fist", and I think it might apply here. Don't see porn as an important thing that you have to desperately avoid at all costs, just recognize it as a boring waste of time and find more interesting things to do. I'm sure there are many different ways for spiritually open people to attain sexual bliss.
