So, a jackass has been saying on a forum that he likes a fetish but didn't want to say which one. Help me resolve this /b/!
He said
> There is something in your body that grows a lot and is NOT the penis.
> Starts with FE
> 20% similar to introduce something like water or air throw the anus but more hardcore.
> A far variant could be Vore but more weird
> You can die if you go full retard, but you can do it all your life if you control it. Some risk years before.
> There is a documental on youtube about a woman with this fetish
> Introduce something inside your body for some hours, it degradates for a posterior feeling.
> I don't know if this matters, but he asked for someone's skin for envolve a book and smell it

Also, he said the name only exist on english.
