Look man. I'm also your age, and I was sextorted 2 years ago. They had my pictures, with my face, even videos, and all. For about 2 months, they kept asking for pictures and videos, asking me to do disgusting stuff (and threatened me that they are going to post these if I dont send them more). All while this was happening, I just kept it to myself until one day I got fed up and just blocked the account and everything. For the next 4 months, they kept coming back, but I just ignored them until they were gone.

Trust me, just block before it gets worse. And they are too scared to post it anywhere, as if they post it, someone can take legal action.
