The first time I sqirted I was 17, and playign with a vibrator. I didn't know what the hell it was. I was scared that I pissed myself... I got up and put my sheets in the laundry and had a shower. Thought that was super wierd.
About a year later I met a guy who was totally into squirting. He told me it wasn't pee and played with me until I burst.
Once you start squirting, it is something you can control. You push away someone before they get you there if you don't want to. the problem I have is all in my head. Because I didn't know it was a 'good' thing when I did it, I have to be with someone I'm comfortable with in order to do it.
I have a couple regulars that I can squirt for... but I'm not all that great at doing it on comand.
Hope this little info helps someone.
