All women are capable of doing it, but not all women are physically able to do it. This topic has been debated for years as to whether it's pee or ejaculate.
I physically can't do it. I just gush.
Here's some interesting stuff to read on it, though.

There is a guy online who teaches it. Google "grapeseed oil orgasm video" and look for the link at pornhub (about 5 links down). That'll teach you how to do it
if you can get the girl to do it.
