I have not heard the term"flapping'... but i do recall my sister babysitting as a 15 year old, two little boys ages maybe 3 and 5.... I walked in one day and one of them was lying on top of my sisters dog, basically "humping" it.... I asked him what are you doing? and his reply was "mash feel good'...and then something I cannot remember exactly, about his daddy and "mash" feeling good....so the particular phrase may be related to individual experience... BTW- I did contact proper authorities regarding the aggressive and sexual nature of the boys and their replies... CPS did step in... That was 20 years ago, and I would do the same again.... Sorry to have gotten off topic, there... But it is very possible that you could have been sexually abused as a child-- and that the term along with the method of stimulation stems from that. As for dealing with it-- how you choose to is your choice-- but no matter what the outcome ( who, what, when, etc.) YOU are still you, and it was not your fault, and you have survived this far-- and you will survive on. Best wishes....
Thank you for your post -- I have not heard the term "flapping," so I cannot say too much about it, though it seems like what you're describing sounds like self-stimulating behavior (i.e. masturbatory) that a child might partake in. While it sounds like you have already been discussing this with your therapist, if you haven't, I would recommend you bring up your concern about this with him/her, as the two of you have a much more thorough understanding of you, and would likely be able to make better sense of this behavior.
I think anxiety can be expressed in a number of different ways.
I have read that people can reenact things that happened to them in childhood.
It is normal for people who have experienced traumatic events to forget details.
I personally have not heard of the term flapping in that context.
I would be extremely cautious about recovered memories in therapy. I have heard that they are not always that accurate. I am not saying that yours aren't, I am just saying be careful.
From a lay persons perspective the depression and anxiety are symptoms of some underlying issue/s. I think you are right to be addressing those with a therapist.
Good luck with therapy and getting closure on your issues.
I don't know much about sexual problems. I don't know if that can cause flapping. But it could be part of a bigger issue. You should see a doctor a phychiatrist or something. Also flapping can be used with other disorders like autism or something. Or it could be a habit or something.
