Stories like this make me so angry. Your abusers were sexist, shallow, selfish pieces of sh** with no sense of empathy whatsoever. They were probably targeting young underage girls. I remember when I was 15. 15 is still such a fagile age. If you have no soul you can take advantage of a 15 year old easily, which is what those insects did. Let me just tell you this: Any healthy man with a functioning sense of pride and responsibility would have been alarmed if a 15 year old threw themselves at them. They would not have had sex with you. They wouldn't have flirted with you in the first place, they wouldn't take you home expecting a blowjob. Those men you met were abusive and manipulative. They did those things, because they are insects who should be thrown into a volcano, not because of you. It's not your fault, and I hope you find a man who is not a perverted asshole who goes around cheating on you with (...)13,14,15,16(...) year olds. You don't have to put up with this, you have every right to break up with a man like that, report him to the police even.
