I do not know what to do. I have made a grave mistake. I met a boy of 15 years on a chat forum and we talked a bit before moving onto Kik, which is a messenger application, I am 20 years old and I was merely joking around. I pretended to be gay and the boy sent a picture of himself and his penis to me then I, stupidly and regretfully, sent a picture of my own penis to him but not my face.
He then said that he lived in the same country as me, I panicked and told him that I was straight and I did not want to continue this. Up to this point I thought that we were merely roleplaying and it would not amount to anything serious, it was a serious lapse in judgement and I did not know what happened until it was too late. He then threatened to go to the police and I begged him not to, eventually he said that he was joking about the threat when I asked him about it. He also said that he did not live in the same country I usually live in when I said that I lived overseas therefore I am assuming that we live in two different countries.
I told him that I would forget everything that has happened and he agreed. He said that he would delete the conversation and the picture I sent him provided I did the same, which I complied without hesitation, however now I am worried if he kept to his end of the bargain. Should I be worried that this will come back to bite me? I have learned my lesson and never in my life have I ever suffered such a serious lapse in judgement.
He also warned me that I better delete everything because his father is CIA and that he could track me down. I am not sure if this is true or not, but I have deleted everything. But will he keep to his end of the bargain? What should I do? Should I tell my parents? I am afraid that my parents would react badly to what I have done, I know I did a horrible thing but at the same they should know what happen so they can be prepared. Do you think I am over-reacting to this?
