How to fight with horniness (TRIGGER warning)

There's a thing I'm thinking about a lot right now. I feel like I've reached a high level of horniness again. Can I somehow reduce this level in a healthy way? Most people would say, just jerk off to let it go. No Fapers suggest: go for a walk, hang out with someone, do a workout. I feel this can't help in a long term. Is there any other idea?

I also realized another possible motivation of relapse behavior. I've said in the past that I also had a problem with gay videos (although I'm str8). They were mostly male masturbation videos. I realized I was watching them for several reasons. Looking at the man's body (comparing) and mirroring the other person. Any ideas on how to healthily stimulate these impulses?

Thanks guys! You're all awesome.
