New vibrator help!

I bought a new vibrator. My other one is horrible. I've used this new one twice. And both times I O I pee myself. Literally. Not squirt. And I'm embarrassed. I wanna keep using it. It's a great vibrator. Exactly what I needed. But now I have anxiety using it. Do I just make sure my bladder is empty before I use it?? I mean I def wanna keep using it cause it makes me O in under like 10 minutes. But I'm scared oh God this is embarrassing please don't judge I'm new to the sex toy thing. My first vibrator I bought just to try and didn't expect it to be absolute shit yknow???
