Pee or Squirt?

Last night I was fingering myself for the first time, I peed before I did but as time passed maybe a half an hour (I was talking on the phone with my boyfriend taking breaks) it felt as if I had to pee. I kept going knowing that squirting can feel like you have to pee. I came for sure and orgasmed for sure, shaking and everything but when I squirted or peed (still not sure which it is) it was warm and smelled like pee when I smelled it. It didn't dry until today and I ended up scrubbing my mattress because the odor was still there. Anyone know what happened, if you can trigger or push on your bladder while fingering or do some people pee when they orgasm or does squirting have a mix of urine in it or a smell of urine. Please help I wanna know how to prevent this in the future.
