i need help please read

I m(16) decided to do something stupid, i was so

h-rny and I really wanted to do “it” with someone, I decided to go on facebook groups looking for walkers, i found this one person. She said she was 18, age of consent in the philippines is 16 “she” was down too, I got the room the next day and then i was rechecking our messages and i found out he was trans, it stated it on the message but i completely missed it, he also used other fake photos, when i realized this he was already on his way to the room, I texted him saying i ordered food im gonna get it. Then i opened the door, i saw him. He went inside the room with me and i said “Sorry i didnt know you were trans, ill pay you the full amount and just leave” he started blocking the door not letting me leave, then he recorded me, i tried to block the camera then he tried open his bag trying to reach for something, So i went back and said “Ok sorry”, Then he said his handler was coming here. At this point i was trying to be friendly with him and joking around so i can get a way to escape, our deal was i pay him ₱2k, i said ill pay ₱3k just let me leave and delete the video (the video was nothing bad it was me blocking the camera and trying to leave) , then i paid the ₱3k he still said I can’t leave and i have to wait doe the handler, he had a mask i was gonna try and remove it off him but thats too risky, then he randomly became calm and got on the bed saying i can leave, he wont delete the video too, then he randomly took his mask off and i was able to take a 2 sec video, couldn’t risk getting caught and i just left, he texted me saying

“im an it student i can locate and track you , ill text your relatives and friends and ill post you using my dummy acc on fb” i didnt reply, then he messaged again saying “done, already posted you. Did you see it”

what do i even do
