If your impression of the male boar is fierce, it may represent a part of you that is fighting for recognition.

If you associate reproduction with it, it's a direct sexual symbol. On the other hand, reproduction has a more metaphorical meaning: that is, giving to a suppressed part of life.

If it strikes you as animal. Then bestiality may refer to the primitive or socially unacceptable oppressive part.

If it is associated with sin or if it is sexually suggestive to you, it represents your own suppression of sexually related emotions.

Wild boar represents aggression. People's aggression sometimes turns towards themselves. So you should find the source of your aggression. For example, men may be related to the Oedipus complex.
