yesterday my girlfriend was allowing her female to run around and decided to introduce her much younger male to her. She placed him on the ground about 3 feet from the female. His "beard" instantly turned black and he charged the female. He jumped on her back and bit her on the neck. (took some time to get him to release) She wasn't hurt but it did shake up the girfriend. My questions: is this kind of aggression normal in males? Also, at what age will he realize "hey, a girl"?
