How do I squirt? Is this right ?

how do I squirt ?? when he's doing his thing, my body starts to shake and I'm like orgasming and I'm shaking / can't control my body. And then I almost feel a release and I can't take it no more. But this release I don't notice a lot come out but I cum. How do squirt? I've noticed it when masturbating aswell.. I have tried it on my own where I'm hitting the climax and I push through my vagina and liquid has come/squirted out I'm abit worried that was wee hahaha, I don't want to try it on my boyfriend and piss on him by accident haha. Am I squirting already? How can I tell 😂😂
