Talk about pavlov's dog! Stop watching that shit and you'll act more normal. You've conditioned your boner to associate ejaculation with those weird themes. Stop doing that. If you brought out a stapler every time you masturbated or used one while masturbating, you'd eventually get a boner every time you saw a stapler. Same thing with this cuck/gay shit.
Because if you get to that point, what you really need is to go on a porn cleanse to get your mind right again.
Just don't look at ANYTHING pornographic AT ALL and don't fap. Do it like 4 to 8 weeks depending on your level of desensitization and then you'll be able to enjoy porn again. If you have a straight SO, have sex with them as much as possible to rewire yourself to associate sex with real, opposite-sex individuals instead of to porn.

I started watching bbc porn like two years ago and pretty much did exactly as OP said. I have no regrets, it hasn't ruined my life or mental health, and in fact I've had a shit ton of fun doing it.
