It’s difficult to know if you were sexually abused and you may never truly know unless your father admits it. The fact that he inquired about your memories and offered an apology may be his way of admitting abuse. It’s also possible that he doesn’t remember what happened because he was high. He may have his own suspicions about being sexually inappropriate with you. That might be why he apologizes without saying anything more. Alternately, it may be that he is too frightened to admit the truth.
Exposing himself to you might have constituted sexual abuse. At minimum, it was inappropriate and wrong. Your knowing about sex acts at such a young age, and his biting your rear end is unusual, both of which might be considered circumstantial evidence of abuse.
Yes, it is possible that you were abused and, yes, you should report these experiences to your new therapist. Rarely do victims have “concrete evidence” of abuse. Even if your memories are unclear, your therapist needs to know everything about your history and what you think may have happened with your father. It is good that you are seeking treatment. It is the best place to address the aftermath of these experiences. I wish you the best of luck. Please take care.
