squirting

Alyssa
Okay, so I can squirt when I use a a vibrator on myself, but as soon as I'm in bed with someone I can't squirt, Idk if it's maybe an anxiety thing or what. Any tips? 
Also on the squirting debate.. when you squirt is it pee or not? Half the stuff I read about it says it's pee and half says it's not.
