Sex question? teenagerr?

Okay, so I'm sorry if this is awkward but I need answers hahah. Okay so I've never had sex before, but for some reason lately I've been wanting it SO MUCH. and i am absolutely NOT the kind of girl who runs around having sex and making out with a million guys. But like lately it's all i can think about, and i want to so badly!! But coming from a christian backround I've been wanting to wait to have sex till marriage, and i dont want that opinion changed! I really really wanna wait, but all of a sudden I can't stop thinking about having sex..!? I'm sixteen almost seventeen, so could it be my hormones? I'm so confused, and I'm just worried I'm going to be put in a situation where I'm kissing a guy and all of a sudden were about to do it, and I go along with it, because its what my body wants but not my head!! And then i regret it forever, because i wanted to wait for marriage and have my first time be special and sacred with my husband! SO please, tell me if this happened to you, and what you did, or whatever. no creepy comments either please.
