Wet the bed

Today I was having pleasureable rough sex with my boyfriend and it got to a point when I started crying which was unrelated to pleasure and then I felt something like pee and it was alot. I wasnt thinking to stop n I never knew what it was and I'm still not sure. Im so lost. It didnt smell too much like pee and then again im not sure. Please give some advice.

Can female ejaculate come from the same place as pee. Can anyone recommend a book?
