I feel horrible!

I'm young, a freshman in college.... maybe my hormones are raging but I have been really tempted to have a one night stand with a stranger... because I really want to experience sex, my body calls out for it. ( please don't judge but I have even gone online to do some roleplay and exchange some pictures) I guess at this point in time right now it doesn't matter that I wanted to save sex until marriage. It goes against all my believes, i don't want my first time to be with a stranger... is this normal? Do I need help?
