I remember my first ever squirt. I was 17.
Severely confusing lol!
My bf was sitting on a chair and I was riding him.. when we finished my bf says "I'm all wet - what is this? Did you pee on me!!? You can imagine the mini panic going on in my head... we both get on our knees and touch it, sniff it.. It doesn't smell like pee.. it doesn't really look like pee either... what is it??
Took a few years before I finally got an answer to that question. To my great reflief (at the time) it was a one off. Mainly because I was being treated to smaller cock (and that ensued for a few years..), also neither I or my partners knew of its existence....
That is until I fell upon an article about female ejaculation. I was 23. Six years of delicious squirting wasted!! ;(
My reaction: "So that was actually my ejaculate!! Woohoo!! Step aside, I need to experience me some female ejaculaaaaaaation!!!"
Been a geyser ever since!

Love it!! Wouldn't have it any other way!!!
As far as sex in public with a squirter, as long as you and the squirter understand the anatomy behing the process, you just need to be careful and continue enjoying life as you like it!
