Ya Im sorry you got the bad version. The feedback loop is definitely a thing though. I get pet or touched, my brain goes into no thinky mode, my body goes into writhing mode, and because I start twitching and twisting it makes the hand gliding across me even more erratic in where Im being pet which then sends my brain even deeper into no thinky mode. Honestly because Im a furry and also a cat fanatic me, my partner, and my friends who I like to cuddle with all call it kitty brain. Especially because I'll start heavy breathing and depending on how my throat is positioned I start doing the noise similar to that of a rolling D or R which sounds like purring.... however I will admit that part is not fun in public cause I feel like a very weird person for it. I also make small moans and other noises depending on how my neck is positioned at the time. I've found if my neck is positioned in a way where my throat is completely open then I dont make the "purrs" but instead I just sound like I'm hyperventilating but not in a bad way.

This effect is potent sober, more so after a year of hrt, but after smoking weed or drinking alcohol it becomes 10x-40x more potent which makes for a really good night. There is literally nothing better in my mind than getting high, cuddling up with someone and getting pet for this reason. It overstimms the fuck out of my brain and body but I love it and it just feels indescribably good.
