I'm not justifying or defending anything about the situation, I'm just going to put an alternate view from personal experience:

I, not understanding my place as a 14 year old deemed to have grown features and a "mature" personality, it never immediately clicked what the consequences of my actions initiating sexual contact with an adult could be. It was just cool (at the time) to have an adult partner which I think society as always let slide. But of course that doesn't excuse the adults part in any of the interactions.

I as an adult now understand that those behaviors were attention seeking behaviors rooted in trauma aided by how I was treated because of how I looked.

But do I put that on the people I saught to engage with?

I don't know.

In the end it's fucked up all around.
