I don't think there is really much I can offer with regard to your concern. But I noticed you had yet to receive a reply to your post. So I thought I would at least acknowledge it.
I think about all I can say, with regard to your fantasies, is we all have our fantasies. And thoughts are just thoughts... nothing more. So, given what you went through growing up, your fantasies sound pretty "normal" to me. (That is... they are perhaps to be expected.)
There's an old saying that goes: "It's a case of mind over matter. IF you don't mind, it doesn't matter." But if these fantasies are of concern to you, then talking with a skilled mental health therapist about what you experienced growing up, & your fantasies, seems to me to have the best potential for resolving any lingering concerns you may have.
