Deep Thunk 🤔💭 What would be more shocking, a man with a vagina in an all-male world or a woman with a penis in an all-female world?

So let's say there's these two worlds with no crossover where people spawn as men or women and grow old but can't reproduce. One day, the all female world finds out that one of the women there has a penis (she isn't trans, she just spawned in with a penis somehow and no female reproductive system but produces estrogen with magic)

And vice versa with the all male world, one day they find out that one of the men there has a vagina and no male reproductive system but somehow produces testosterone with magic).

What do you guys think would be more shocking to discover?
