Ok I didn't really know what topic to put this under so I just stuck it here. The reason I bring this question up is because my husbands youngest brother is 8 and I watch him and his friend that's 8 too all the time. I'm like their big sister. So one day they accidentally tell me they have been looking at porn. At first I was a little surprised because they are so young. I wasn't mad but I decided the best thing to do would be explain what sex is in detail. I'm training to be in the medical field so I got out my text books and showed them diagrams and explained the entire process partly because they kept asking me questions. They were very confused by porn and had some weird ideas that I had to clarify but in the end they were really interested and now my husbands little brother says his favorite cell in the human body is a sperm cell and he wants to be a urologist and study them when he grows up. My question I guess is if a kid is curious about sex is it better to explain to them what it is or not tell them at all? And when do you decide to explain it to them?
