I remember having chicken pox when I was about 8 or 9 years old & sitting at home with my mother watching TV.
Back then about the only thing on daytime TV was the educational programmes for schools.
Anyway this show starts and it's about puberty & childbirth, and my mother figures I'm about the right age to learn about this stuff so she lets me watch it.
So they get to the bit about the sperm fertilizing the egg and they have a camera shot inside some womans womb with this huge gushing tidal wave of man-juice engulfing it and I say to my mother 'That looks like it might hurt a bit'
She shuffled uncomfortably and says 'Actually it feels quite nice' and walks into the kitchen before I can ask her any more questions
