First time user

I just tried the diva cup for the first time and it went way up that I had to ask my husband to assist in removing it. It was horizontal and he couldn’t find the stem. When I inserted it I left the stem out. Is it that I went in too deep? Because I could have only touched the tip of the stem while hubby couldn’t find it at all or maybe he was in panic mode cause he kept saying let’s go to the ER😂 so should I put in the cup halfway or all the way in? Or just the stem should be out? I don’t want to give up on using it as yet. Help please.
