i know what you mean, i've wanted that too, but by accident it actually did happen to me (the actual slut had the same name as me) and i realized how horrible it made me feel. it makes you want explain yourself to everyone you meet, tell them not to judge you.. it doesn't make you feel safe. it makes you feel like every guy is just after you for sex, or they are only thinking about sex when they see you, and every girl is talking about how disgusting you are. it didn't make me feel cool.
i hope you can get some insight from my experiences.
