Pool: The birds and the bees
Can also be known as "The Talk".
This pool is for 2 purposes.
1, when characters give the talk.
The talk can be divided into 2 main stages.
1A. When a character asks how babies are made or about sex
1B. The explanation itself of sex or baby making.
The explanation can be truthful, where they talk about semen going into an egg and such
Or it can be a more child oriented explanation, like about the stork or the birds and the bees.
you don't have to have both the asking and the "talk" in the same picture but it must be obvious what the situation is.
2, When the characters are so oblivious to how sex works, they DESPERATELY NEED the talk.
ex: 2 women worrying about getting each other pregnant (just assume they can't become futanari's unless stated otherwise)
