Am I Squirting?💦

So at the age of 19 I've just started to become familiar with my body and discover what I like. I am sexually active but have never been able to orgasm because I always feel it's too intense and I wriggle away. However I was just rubbing my clit and I felt a build up of pressure but then suddenly liquid squirted out? It is very watery and not like CM but I'm worried that I peed myself because it is a slightly yellow colour on my white bed sheets?! I didn't feel an orgasm at all but as soon as I squirted all my sexual feelings went away and I stopped. 
So basically, was this release of fluid because my body was enjoying what was happening or did my bladder react and pee myself? So confused and if it is pee I don't want to be letting it go in front of a sexual partner!Â
