What is the Meaning of Innocence?

So today at lunch a new friend of mine named Hannah told me I am very innocent. Many other friends and people in my class have told me this also because I tend to keep a clean language and reactions to certain things. Well she told me that her step-mother was very innocent at age 14 on her first day of High school (I am 14 and I'm in 8th grade) and a few senior guys were flirting with her one of them I guess became her boyfriend and had you know what with her and left her after two weeks of being her boyfriend. She also told me there is a good chance this will happen to me. I don't think the cause of this misfortune was innocence ,but no self control, and peer pressure . Also obviously her step-mother wasn't that innocent. This can happen to anyone dumb enough to have a senior boyfriend and let him take advantage of you, not innocence.
