There's this girl who is constantly hanging around me and my friends. She is completely obsessed with , and it makes everyone really uncomfortable. With her, the conversation is always masturbation, , or just flat out . She hasnt even had , but she acts like she has She also is very loud, and im thinking Histrionic disorder? also, she thinks were best friends and tries to hold my hand- one time I swear she tried to kiss me, and shes tried to kiss my other friend too who is also a straight girl. Then she wonders why everyone thinks shes so dirty. So what is this girl's issue? could it be histrionic or something else?
