@aureainjail Moisture is scarce in the female butthole, like Arrakis in Dune. Spit is invaluable to them, like the Fremen in Dune. You have to slowstroke the butthole to penetrate, like the bodyshields, in Dune. To stay safe, you should navigate the hole in a specific rhythm, like in Dune.
Ideally we would all like to have sex with ourselves. Next best thing would be a family member. Those are not possible, so our third option is a stranger who gets "close enough"
I saw an insane and stupid take but I just ignored it because the person was 23, which is emotionally and intellectually equivalent to being 16 years old these days.
