Hi everyone! I’m 21 and have never orgasmed during sex..

So i can orgasm with my fingers or a vibrator while watching porn and sometimes just imagination. Last night I hooked up with this guy and he was going in really good and I felt something soooo goood and he kept going- I felt the build up but i wanna like “release” but I couldn’t for some reason and then I have a feeling to pee when he slows down..

What does that mean??
