This is an interesting topic to me because it reminds of the time I celebrated my 15th conception day. The festivities were so wonderful, I wish you all could have been there. We played pin the sperm in the egg (I TOTALLY missed!) and had a really big conception day cake.
The thing is, the celebrations and games were so much fun that I got so excited and accidentally killed a bunch of my sperm cells. I was embarassed, of course, and my mom and dad were LIVID! I had to endure another stupid lecture wherein they told me that my sperm, while not developed, were essentially human. They asked me if I would kill a 2 year old because it wasn't an adult. I replied, no, no, of course not. They asked me then how I could kill something that would be human someday given the right circumstances and enough time to grow. I didn't have an answer except to ask why so many sperm had to die during normal intercourse (I read about that in a book I wasn't supposed to read!). My dad got all red in the face and told me to go to my room and think about it.
That night, I killed more sperm cells in my sleep. It's hard for me to tell this to all of you, but it's true.
