G spot and squirting

So one time when me and my boyfriend were having sex, we had the light on and I looked down and I had squirted? But it was only like a little splash it wasn't a lot, and that's the only time I've ever seen it.. So I'm not sure if I can make myself or not? People say for my boyfriend to rub my g spot and i will? He had fingered me and did what every one said.. Use a "come here" motion with your fingers, but it just felt weird and I still didn't squirt.. I'm just confused at this point!
