I struggle with this too. My ways of "managing" it are probably worse than the hyper-sexuality that I was trying to stop, I'm yet to bring this up with my therapist but we are edging closer towards talking about it. I isolate myself, I've put on weight and self harmed as have found that body shame is one thing that "works" to stop me. I find I am very easily influenced if someone else wants sex, so the isolation helps to reduce the likelyhood of those encounters, and making myself less attractive also helps to reduce the amount of attention I get.
I don't have any healthy ways of managing hypersexuality. Maybe my therapist will be able to suggest some things whenever I can force the words out of my mouth to actually talk about it. I'm not prudish about sex, but the hyper-sexuality meant I was putting myself in unsafe situations, having unsafe sex, doing things that were not in line with my morals, triggering myself into bad emotional states etc...Not healthy stuff.
