I can understand how awkward this situation is for you, and your family. I'm no expert but can at least share my opinions.

Teenage boys are known to ********** frequently but a lot of people can't perceive that girls have the same "natural" desire to do so as well. Maybe it's because our generation was brought up to feel that women aren't as sexual as men, but who knows. In some ways, I feel she is "normal" in finding ways to pleasure herself and maybe even "using" the dog to relieve herself of the guilt of pleasuring herself by her own hands. Something else you said concerns me and made me think. You said that "smacking" her didn't help. It's not up to me to judge whether it is appropriate to hit, spank, smack, etc. Doctors are noting that it is very unhealthy mentally. It is ultimately up to the parents to decide whether it is right or wrong. Now, believe it or not, I know a grown woman who admitted to me that she has an "animal fetish". She told me that she is involved with a group of people who participate in sex with animals, both men and women. The thing that most of the sexual receivers shared was wanting to be dominated or humiliated and some felt that their bodies were not good enough for a human. Maybe she is experiencing this due to a reaction of being put down somehow and the humiliation she feels when she is smacked. (please don't be mad, I just want to help) If it were my daughter, I would ask a professional no matter how embarrassed I was. They have heard it all, believe me! At the same time, I would try to build up her confidence and hope that her sense of self and security will lead her to a "real" relationship. Does she date? If so, how are the guys she dates? There's usually a reason that people have extreme fetishes, most come down to insecurity

I can sympathise with your embarasment but your willingness to talk about this has spurred me to write this. At about the same age as your daughter I often did the same with my family pet. For me looking back I would have to say i did it because I didnt think myself worthy of human atention. I would have been mortified if i had been caught and think it may be worth talking to your daughter to see if there may be an underlying cause without berating her for her actions, knowing how much you diagree with it may mean it is now a cry for help. Punishment will only reinforce the feeling of self loathing. I eventually stopped when my self confidence and opinion of myself increased.
