Although I am not personally able to achieve this, I have heard of women who can. I have talked to a couple of (believable) women who claim the ability and I have also heard it from an (equally trustworthy) man telling me about his ex-girlfriend’s ability to squirt. I do not doubt that there are, indeed a few women out there who can do this. I join you in wondering how it works, exactly. Further, is it a learnable ability?
