That's about how it went with me too :-)
Seriously, though, I remember many lessons from his heart-to-heart with me. First, losing one's virginity is not a race. It didn't matter what stories were told about which girls in the locker room. Being armed with information (and by that, I mean graphic physical descriptions of anatomy and process) helped me understand that 90% of those stories were BS anyway. And the other 10% did not involve a gentleman, or they wouldn't be told.
Second, it taught me that my father trusted me, not to be perfect, but to be aware, discriminating, and prepared.
Thirdly, when "the day" finally arrived, I was more emotionally settled and, while there was a certain delicious guilt surrounding the event, I wasn't terrified of subsequent health or pregnancy issues.
I think the talk was the beginning of that transition that all men hope to have...when your Dad becomes your friend. I treasure my relationship with Dad, and strive to duplicate that relationship with my own son.
