"Dad, what does a vagina look like?" joke

A young man walks over to his father one day and asks if they could have a talk about sex. His father agrees and is eager to help his son with any questions he may have.
"Dad, what does a vagina look like before sex?" asked the son.
"Well son," answered the all knowing father. "A vagina is the most beautiful thing in creation."
"The soft folds of a vagina are softer even than the petals of a rose."
"The delicate scent of a vagina is finer than the finest french perfumes."
"The taste of a vagina, is sweeter than the purest nectar."
"All in all son, it's like I said, a vagina is the most beautiful thing in creation."
"Gee dad, a vagina sounds just great, the way you describe it."
A few moments of silence go by, then the boy asks another question.
"Dad, What does a vagina look like after sex?"
"Well son, have you ever seen a bulldog eating custard?"
