Are sexual interactions between brothers normal in childhood?
I just remembered a confession my little brother made to me when we were younger. I have two younger brothers who are two years apart and shared a room for their entire childhood. The younger of the two told me that they had put their mouths on each-other's privates one night. I was pretty disturbed and told him that was incest. I kind of forgot about it afterwards and only now remembered it. Is this normal, curious behavior for younger boys?
