I can’t orgasm anymore 😩

Lately I have been getting less and less sensitive to the point where when I do orgasm it just sort of fizzles out and feels like NOTHING. Could it be from stress? Maybe shame? (i know masturbating is normal, but as I begin to explore kinks and stuff, much of which is depicted very violently or unrealistically in porn, I get turned off and feel disgusting... I try navigate to find the least offensive video or just try to ignore the hardcore parts of the videos i do watch instead of being able to enjoy myself). I don’t even like masturbating anymore because I know all I have to get off to will be these extreme, often dehumanizing porn videos. Has anyone experienced/ know how to remedy this? Do you guys know any sites I could try?
