My 6 year old son son licked his step-cousins butt and then kissed his penis. He then told the other child who is also six not to tell. The other child told his mother. My sister-in-law and brother-in-law now will not allow my son around their family. He was 6 years 5 months when this occured with a child who is also 6. When asked what happened we were told by my son that his dad's neighbor, another boy who is 6, did the same thing to him. I've taken him to the therapist and school pyschiatrist and they don't see any signs of being sexually abused. Is this something that occurs with six year old boys or should I seek further intervention? It's basically broken our family apart.
