I know it is common for young children (ages 6 through 10) to engage in sexual play. In my parenting days it was called "playing doctor" and usually involved looking and maybe touching "private parts". However, there was an incident within the family where a couple of young boys engaged in more advanced behavior. One had the penis of the other in his mouth. At first this raised immediate concern that perhaps one or both of them have been bothered by someone. However, both are well adjusted, smart, happy go lucky 9 year olds who are actually quite innocent. Neither boy has been subjected to improper media as far as the parents are aware. I began to wonder if this might be normal sexual exploration in todays world. Since oral sex has become so prevalent among middle school age children, it made me think that perhaps this information has become common enough to trickle down to younger children. Is this naive thinking? Should their parents be more concerned or can it be handled as it always has, through healthy communication and sex education appropriate for their age level?
