Squirting?

Abigail • 21, married, happy ❤️
I'm 18 and I started having sex about two years ago. I've only been with three guys and it's always been easy for me to orgasm. Like, it doesn't matter if it's oral or vaginal sex, I can orgasm multiple times without hardly any stimulation. My boyfriend and I have been together for almost a year and we do stuff a couple times a week and I've never squirted before. Until last week, he was eating me out like he usually does and he said it felt like I peed but I know I didn't. Well tonight I was masturbating with a vibrator and it happened again. A bunch of fluid just came out and I don't know what to do. Is that squirting? Because I've never done this before and I've been sexually active for long enough that I would think this would have happened sooner if I'm able to do that. 
Help please!
