im going to disagree with the above posters. the being 19 and not having a boyfriend isn't something to worry about. but sexual urges involving violence and animals? i consider anything that hurts another being an abnormal when it comes to sexual urges. especially a defensless animal who cant say whether they object to it or not. thats why beastiality is illegal. i agree that you do need to seek help because these feelings can turn into actions and those actions might lead somewhere else even to the point of raping someone - but i dont know how much youre into the violence part. i would see a therapist to find out why youre having these feelings. ask them if they think its normal. everyone in here is going to have their own opinion and i think the only way to get a clear answer is from therapy.
