Water Works

So I was getting busy with my man. He's my first so I'm still getting used to what it's like with him. I've had a vibrator and know how my body responds to that but it's different with him. We've had sex a thousand times before and I never orgasmed with him. But then I'd come home and finish with my toy. 
Tonight was a different ball game. I got so wet that I thought maybe he had finished meanwhile the pressure was building and all of a sudden I felt like I peed myself. I was confused on what exactly had just happened. Did I squirt? Did I pee? Was that my orgasm? It wasn't like a full body orgasm that I can't control with my vibe. Just the pressure building, crazy wetness, and then the feeling disappeared. 
Someone please explain what the hell had just happened. 😅
