That's good then. I get the point of your post but I, again, hope your friend comes out and uses this as a tool to educate others. Unfortunately everyone thinks they are invincible until they are truly hit with a hard dose of reality, not even as severe as this. Sometimes its the simple fact of seeing a peer in a specific situation that puts it all into perspective. There will still be dudes (and girls for that matter) that will continue to be shitty but if this story effects even one or two other people and convinces them to change their ways, then he will have made a difference.
Also, I hope for the sake of the community, anyone that was unfortunately infected by your friend or the person that gave it to him, they follow the same steps instead of trying to hide it.
