Mathematics, needlessly lewd
so if you made a Klein bottle out of silicone, such that you could use it as a sex toy, you would never actually be fucking the inside of the sex toy

@Leucrotta Now I wonder if you could redefine the concept of "inside" to make sense here. 'Cause clearly your penis would /effectively/ be inside it, even though it's not in a topology sense.
re: Mathematics, needlessly lewd
@frostwolf we’re watching this thing about Klein bottles and they technically have only one surface with no edge, and so technically using a Klein bottle as a sex toy would be less like fucking a fleshlight and more like rubbing off on a towel or something
re: Mathematics, needlessly lewd
@Leucrotta Or, would you be not just fucking the inside but also holding the inside of it as well? :3
