Pre mature climax

Ive attempted to quit watching porn with varying degree of success, I still relapse every now and then but definitely not as much as once was. I’m not fully against watching it but personally I need to stop.
Anyway, I’ve found that I while I’m pretty good at maintaining an erection or getting it up multiple times, I climax really fast now whether that’s sex or masturbation. Anyone else have similar experience and tips?
