How to insert a tampon if you are a virgin?

I watched so many videos related to this topic but I am still scared. I tried to put it in and I did it (put the aplicator in till the grip I was holding) and heard, no not heard, felt a pop. What was that? Also, I had to put the whole thing out because the aplicator was made of cardboard and it absorbed a lot of blood before I figured everything out 🤔
