Okay, don't quote me on this because I may not be correct, and I under no circumstances have ever made my girlfriend squirt but here's what I know about the subject..
It's not a myth. Very real indeed. The mixture in the bodily fluid is coherently types of proteins, as well as small amounts of urine. This feeling in a woman can be unpleasant to anyone new in experiencing female ejaculation simply because it feels similar to urinating. If a woman is not comfortable doing this, she can hold it off.
To achieve this, you must stimulate a ****oral and g spot orgasm simultaniously and reach multiple orgasms..I know I know, a lot of you guys have probably done this, and don't get discouraged. A lot of girls won't be able to achieve this like some of the others said. Like I said, don't quote me on this stuff..I'm not an expert. This is just what I know about it.
