'At a very young age, my daughter asked me what the differences are between a male and female's private parts. Can you imagine how worrying it is to be a father these days? I am very open to discussing with my daughters what sex is, but not in full detail, of course. Sex education should be included in the school curriculum because I believe it is very important to teach children the correct attitude from a young age. I also don't allow my daughters to go on the internet alone because once I received a spam e-mail of a naked man. I was so shocked I deleted it immediately. Since then, I won't let my children go on the internet alone.'
