Without preamble may I present to you a letter from father to daughter on the joys of sex.

Okay, maybe a quote:

"Yes, all these boys and girls and genderqueers may break your heart, and that in turn will break mine. I’ve held you, sobbing, after your boyfriend cheated on you, and it tore me in two. But you know what would tear me in two even more? To see you in a glass cage, experiencing nothing but cold emptiness at your fingers, as Dear Old Dad ensured that you got to experience nothing until he decided what you should like."
