Well, sadly Charlie has earned the nickname
"Hit and run Charlie" because he will run up very quickly hump a couple times and then run off
He is fixed has been since 6 months of age but I have no idea how to make him stop and he only does it to a couple people (my mom LOL, my husbands brother, and a friend of my husbands) when we see him doing it we says NO in a firm voice but it doesnt seem to help, he doesnt bother with stuffed toys.
