Well this was my logic. This Amanda girl apparently forgets a guy underage, that sounds pretty sluttish to me. Or..is that not sluttish?
Girls having love with someone doesn't make them a slut. Your logic is stupid and if you continue thinking that way you're on the path to being alone for the rest of your life, girls like being respected and judging them so harshly on a mistake they made is not a good thing to do.
I hate to introduce the most common double standard regarding this topic, but think of it this way: if you had love with a girl you were or weren't dating while underage, would you think of yourself as a man whore? Of course not! "If girls have love, they're sluts - but if a guy has love, high fives all around!" It's a disgusting way to think but sadly it's quite common.
