Penetration Pee Signal False Alarm

Vika
Anyone else need to pee during penetration, and by needing to pee, I mean I NEED TO PEE RIGHT NOW needing to pee, only to find nothing coming close to a resemblance of that feeling upon sitting down on the loo? If it has happened to you, did you ever figure out why, and were you able to figure out a way to resolve the problem? Help!
