What if I squirt in his mouth?

I can't control when I'm going to squirt. Sometimes I can feel it coming, but even then sometimes I don't squirt, or I'll squirt when I don't think I'm gonna. What if my boyfriend is going down on me and I have an orgasm and squirt in his mouth?? I know that squirting is pretty much urinating... I don't want to pee in his mouth! 
Bonus question: what do girls find so pleasurable about squirting? For me, it literally just feels like a normal orgasm but it feels like pee comes out. I do not like that at all. I don't know if you've ever accidentally peed on your hand or accidentally just touched pee, but it does the same thing to your vagina that spit/water does and makes it hard to masturbate and very not pleasurable. Or, at least, that's how it feels for me.
