No, not at all. the whole thing just strikes me as really odd. You have been searching for memories of abuse from your mother and then suddenly you reveal this really inappropriate stuff with your father right here.
Rather than the possibility of you lying about it what I wonder more is this:
That maybe your parent/s (certainly your father and maybe your mother too) have been covertly sexually abusive towards you. Covert sexual abuse is where instead of obvious acts of abuse a person repeatedly invades personal boundaries and makes sexually inappropriate comments or gestures so that you have a very clear sense of something being "wrong" but have no clear memories of acts you can absolutely say "that was abuse".
That kind of scenario could well lead to the symptoms you are experiencing. A lifetime of that kind of inappropriateness where you know something isn't right but are so confused about what exactly is wrong can really, really screw with your mind.
