Why would I tell my parents about that? If something really only relates to my private life, why would I burden my parents with it? I don't want to compare this to an ordinary kink like bondage, because I feel like that won't land right, so I'll explain it like this: if I were gay, and liked fucking men, but had zero intention of ever being in a relationship with one, meaning it only has to do with my life behind closed doors, telling my parents about it would basically amount to: "hey, mom and dad, I want you to know that I like taking random guys home and fucking them. I feel like it's very important for you to know what I use my penis for." It's just weird to do that. And, honestly, it would be weird to do that, even if you're straight, it's just that coming out isn't something that straight people ever have to think about, so being gay felt like a better parallel. If something is unrelated to my public life, my parents don't need to know about it, regardless of how accepting they would be.
