IPhone app to lock iphone apps?

I know it looks weird, but the question is there an iPhone app or something to download that can lock my other iPhone apps? Say I use that app, then when someone tries to open an app on my iPhone such as Facebook, they would need to put some sort of code or need to unlock it in order to access the Facebook app. Because I don't like to put a passcode lock on my phone. So if I turn on this app lock iPhone application, people will need an access code. Do you guys get what I'm saying? Sorry if it sounds confusing, but I really need to know. I have an iPhone 4s by the way.
