just trying to research here about if my identity has been formed or I am made that way
I wouldn't bother. You are who you are. Knowing that 56% was the result of your early exposure will not change anything. Are you happy with your identity? It seems so. Then don't worry about it.
While I am concerned about the difference in age from what you wrote about (and it was wrong) that does not mean that it has effected you so too badly. Yes it has an effect but was it the cause of any issues you have problems with? If no then you might be able to just keep it in mind but put it in the past.
There was no violence in my story (that I have not told yet) but there was manipulation and I never wanted it. That's a big difference. You seem to have wanted to explore you sexuality early in a non manipulative situation. (the first)
Do you have a negative self image? Do you have any trust issues? (I can go down the list) If you don't have any big issues (that you know of) then I would not worry about it if you can be happy and enjoy your life.
And what I wrote is likely worth what you paid for it.
