Even harder to find on the web than positive memories are the testimonies of girls who wanted to have sex with older guys,

Um, maybe because such testimonies tend to be "flagged" as "innappropriate" to the terms of service agreements of just about any website, blogging system, or social media platform in existence? Because girls would get in severe trouble, from having their accounts deleted by the site administration to having what few freedoms they have taken away by their parents, for posting such feelings/revelations? I understand that advocating your point of view requires ignoring everyday common sense, Ethan, but the political situation regarding younger people is quite well known to all who debate with you and all who read these debates, and we all know that you know it as well as we do.

but they refused because it was illegal, and the girl felt seriously harmed.

People tend to feel seriously harmed when their choices are denied them. Because they are constantly forced to seek out the "next best" choice, constantly forced to settle for someone else's choices, and constantly forced to live as an individual without agency. People do not like being controlled by others, and denied freedom of choice is the ultimate form of emasculation. People who would make different choices than you would do not see things from your perspective. This is Human Psychology 101, Ethan.
