OMG Kinsey!
I was watching the Kinsey movie and it contained the following exchange during one of the interviews:

Interviewer: "How old were you when you first engaged in sexual activity with a partner?"
Man: "14."
Interviewer: "How?"
Man: "With horse."
Interviewer: "How often were you having intercourse with animals at age 14?"
Man: "Is true. I fucked a pony. You are genius. How did you know?"
Interviewer: "You just said you had sex with a horse."
Man: "No! Whores. Not horse. Whores."
