I had a vasectomy. My kid asked if I still ejaculated and then after getting the answer asked if it was the same (the output). Just be honest and open about being normal biology. It is not that difficult.

I was almost 4 when my sister was born. On the ride home, I asked my mom: “Now that the baby is born, will your periods start again?” Kids understand basic biology when you take the time to explain. It’s the bigot parents who get all traumatized talking about it!
