Well, there has been some research on female orgasm- the chemicals it releases, etc. Apparently, it even helps with conception, because during orgasm the cervical muscle contractions help pull sperm into the uterus.
But as far as "squirting", there hasn't been too much research.
I think they've broken down the chemical composition of female ejaculate, and that's about as far as it's gone.
None of the chemicals in it are particularly toxic, so I wouldn't think it actually has
to be "released" on a regular basis... but if it makes you feel cleansed and healthy, as the original poster stated, then go for it!
