When I was young I saw a dog having sex with my beagle. I didn't know what was happening and asked my mother what they were doing. She was clearly upset and said we have talked about this before, I will tell you tonight. It was clear to me that asking was wrong. We never ever had a "sex talk" that I recall. She gave me a book with diagrams of men and women and the development of a fetus. Not so very informative about what I wanted to know. I found The Joy of Sex in my local library and that was how I learned about sex. I am glad the librarian didn't call my mother. My mother would have had a seizure.
