I legit do not think jerking off to porn is good, that being said, I still have some saved in my computer and watch them occasionally, I am working on fully dropping porn eventually tho.
You should not jerk off daily, at all, and when you do, you should use imagination, some ASMR audio, or at worst, softcore-vid, instagram/softcore pictures of a girl you like.
Jerking off to porn is a super-stimulus that will fry your dopamine levels, can lead you into a rabbithole of always searching for something more nasty, and is essentially virtual-cuckoldry, you are still watching another dick, another man fuck a woman you wish you were fucking.
Besides that, porn can also easily warp your views on relationships, sex and love, so always remember: You are watching whores fuck/perform for money.
Those faces, positions and things they say is for money, there is no love, or any romantic feeling involved.
And if you call me a prude, I will tell you I have been jerking off since I was 15, daily unless I had a girlfriend, multiple times at a day too sometimes, but since semptember of last year, somethings happened making me reflect and get insight on how porn was ruining my life and my cognitive.
I won't be preachy anymore, as every person deserves to make their own mistakes, but theres a reason why so many men, even successful ones, like Kanye, Louis CK, Chris Rock, Terry Crews... succumb to porn addiction. This shit is poison for your mind.
Porn is too easily accessible. Too easily comsumable. Too stimulating in the wrong ways. Is literal crack for men's cognitve.
You consume porn to fulfill some needs but it just makes you hungrier feeling more empty afterwards, is like drinking salt-water to kill your thrist, insanity.
