Something in life ; you never understand ?

Question

An old man said to me once he can't understand that in the tradition of a country ; the first night of marriege ; the husband uses his finger instead .....!
This country is in Africa .

Answer 1

Maybe to see if she's a virgin? Maybe to try and prep her for what is next. Sounds weird, but customs are customs.

Answer 2

If they practice FGM in that country, too, it would be because her parts are too small for intercourse and need to be primed.

And if I say any more, I'll feel really sick.
