"You have a fiancée." What if your parent suddenly tells you that…? Are you anxious because you don't know what kind of girl she is, or are you excited? What if she's incredibly cute and kind, and seems like she'd be great at teaching dirty things, and much older than you…? Having a fiancée means it's practically guaranteed that you'll have sex with her. Since you can have sex after marriage anyway, there's no problem with having intercourse now!
