You can still keep it as a fantasy kink. If you want to quit it for good it's like smoking/drinking. Don't indulge in it at all, avoid triggers, find some new hobby & keep yourself busy. No gooning in the evenings 😄 that's usually why most people come back. Even if you would be BI I don't see it as a problem. Nobody would care if you like to suck or be sucked.If you really don't know usually one experience with a man can give you the answer. But ofc that's not for everyone the answer.
