Please Help!!!!

So me and my fiancé are getting married next Saturday! I'm still a virgin... STILL! I've never worn a tampon (always wore pads) and I already told him I want to have sex with him our wedding night but I'm scared, he told me I don't have to, I really want to but I'm so scared. I'm worried about the pain, plus I never had anything down there so I don't know what to think! Will it hurt? Will I bleed?! I just feel so anxious! Any advice on how it feels? I want to do it. I just need to hear about everyone's first time.
