What I love about female ejaculation is that it's usually a fantastic surprise and only happens when the sex is beyond good and hitting nirvana!
Of course it's rare...maybe that's how we know we've found our soul mate. Or sexual equal. It's definitely worth striving for, and yet it remains elusive. I've only been there a few times in my lust filled wild sex life.
And yes, I would think all women are able to have an ejaculation. Why wouldn't we? We're all hot wired to enjoy the sexual act to the maximum, however we percieve/perform/express/unleash it. Once you totally let go, orgasms take on a life of their own!
An once you have them you're never satified for less.
