Really one of the coolest things ever is how easily you can shape your non-volitional responses by choosing to respond in a certain way.
Like, if right now you don't make any noises in response to sexual stimuli or pain or whatever, that's fine. I imagine you might even have some trauma to work through. An environment you needed to be quiet in, a belief the sounds you did make were inappropriate, or some other taboo against noise.
But, you can change yourself. Rather easily, too. Just start making the noises you wish you made. It'll feel silly at first. Well, maybe it'll feel hot at first, too. I highly recommend perceiving it as hot. But it'll feel performative in any case.
And if you keep going, it'll become automatic. You'll shortcut the process. You'll forget to notice the intent. Learn to use it and use it without thinking. And eventually you'll have to stop yourself from not using it.
Plenty of the time it's actively beneficial too. Helps with pain tolerance, and I'd expect other kinds of sensitivity too. You're a social animal, it's comfortable to perform a social component. It's useful to do so for just your own mind.
Also, like, loudly moaning is really hot.
i did this for tickling! i used to be someone that would just squirm and make faces when tickled. the idea of someone seeing me smile or hearing my laugh felt so wrong to me. i still dont know why i was that way. at some point i just had to give myself permission to laugh, and while it did feel forced and weird at first it really didnt take long to start feeling natural, and omg it feels so good to just let loose and laugh my ass off now!
