I am a very sexy and beautiful girl. I have very strong sexual desire. Once I saw on the internet a woman having sex with her pet dog. Whenever I wish to have sex with my dog, I close myself in my room with him and have sex for one hour or two. I am satisfied up to orgasm. But my worry is whenever I have sex with him he discharges his semen in my vagina and I also enjoy the same. Is there any issue taking his semen inside. Another problem is my mother now suspects our relationship. She has started behaving strangely with me and keeps eye on me. But I can not stop myself having sex with him and he is also very fond of me. Please advice.

This is unnatural and not desirable, medically as well as socially. You have to control as being an animal dog is not going to control.
