In highschool and early college running trains on a slutty girl was not out of the ordinary. These girls mostly do it out of peer pressure and because of validation issues ( but they are also attracted to the guys too).Yeah their called sluts, Pan87 is such a square he thinks there's no such thing as sluttty women
I know that you know about this but I guess Pan87 did not do this in highscool ( again no offense to him). Are these girls the most healthy mentally...no probably not. But it is fairly common especially among young women.
I did something like this once and me and my friends almost ran a train on this other girl before his mother came home. We were basically stupid teenagers. I regret it. My vibration was low back then.
