So, apparently patgasm is an actual thing and and you can just get off via headpats....I can confirm. While some girls do touch themselves after inexplicably getting turned on by being headpat, most of them have a patgasm purely from the headpats.
Also, as a reminder, I'm a horrible person:
"What should I do instead?" is what it says immediately after you select the option to stop headpatting.
I swear, why do we keep getting turned on by VERY ordinary things or actions ?
