New cup user


Hi ladies! I did the "put a cup in it" test and selected a cup from the suggestions. I purchased one while on my last cycle but they ended up sending me the wrong size so I had to wait to get a smaller one. Once I got it, i was pretty much at the end of my cycle and also got more busy with work, so there was only one time i really tried to insert the cup, which i was never successful in doing. I am starting my new cycle soon (feeling like it will be tonight or tomorrow) and I'm eager to try again, however it kind of feels like I'm really having to force it. Is it normal to need/use lube to get the cup in?
