Personally, I don't think this particular thread should have been here, I really don't understand the implication of your purpose in posing it up in the first place. However, may I suggest that even if you would like to share with us your life experiences, we'd prefer something that we can all learn for the betterment of our future and maybe perhaps in the future, be able to use it for ourselves which not only benefit us, but would also benefit ALL the people around us.
I am not saying that I can pass judgment on you on whether you are right or wrong, since only its up to you and the Almighty. Hence, I pray that you may seek what is right in accordance to your religion in your future, or whatever time that is left.
Allow me to end this by saying that there are many methods in helping the 12 year old kid who lives in a world of poverty. The methodology is vital as it reflects upon how much you care for the person, and this could be expressed and done in the form of getting her out of the current world, take her as a god-daughter, or if you feel the responsible is too heavy, maybe take her to the social welfare department, or try to reunite her back with her family. These are methods which are socially and culturally acceptable. We would not want to do something unacceptable since it may destroy the norm and henceforth leading to certain punishments and judgments imposed on you by the authorities, and when that happens, its your life that would be hanging in the balance.
To balance the risk of enjoying the satisfaction from sex and also getting apprehended by the authorities, I think you do have a good insight to think it over and come out with a good conclusion.
