When a girl squirts, its actually not vaginal fluid, but straight up pee. When her pelvic muscles contract during an orgasm, she might empty her bladder so don't even think about drinking it, specially if you don't know where they came from. If you do want to try getting peed, try it with a partner you trust and make them drink lots of water, no flavoring, and don't let them eat salty food for 8 hrs before you do it.
