Important question!!

So, I have touched myself before and my boyfriend has touched me (I'm still technically a virgin though) and every time I "finish" a lot of fluid squirts out. I get really worried that it's pee but it doesn't look yellow or anything, but it smells odd? I'm just scared that instead of releasing myself I'm relieving myself on my boyfriend!!! I've used the bathroom before we do things and after, but I'm still unsure. How do I know???
