If someone ejaculated in water that you was in at same time but you didnt have sexual intercorse could you still get pregnant?

I assume you are in a bath tub or Jacuzzi or swimming pool or in a shower. In this scenario, the ejaculate becomes VERY diluted and if you were in a shower, it gets washed away immediately. In any case the chances that enough material gets into the female tract is infinitesimally small except if the ejaculation occurred within few inches of the female private part and even then the chances are still VERY small. Overall the chances are too small to be worrisome
