Female Ejaculation?

[sickofyourbs.livejournal.com]

So by some fantastic miracle, I have figured out how to "squirt" just about every time I orgasm. It's fantastic, and the husband loves it. It's not a whole lot (nothing like in the pornos), but he still thinks it's hot, and I'm pretty fond of it myself.
My question is this: Usually the 2nd or 3rd orgasm, it starts to smell a little bit like urine. I know with men, it is physically impossible to urinate and ejaculate at the same time. Is there any fun mechanical rule like this for women? I've also read studies that say female ejaculate likely comes from some sort of secretion of the bladder that is not urine. Maybe after a couple orgasms, I'm out of that fluid, and I'm getting a little urine instead?
I guess my question is, urine or female ejaculate? I'd really rather not pee all over my husband after the 2nd or 3rd orgasm, ya know?
Any info would be much appreciated!
