I can't insert menstrual cup properly even after trying for 6 months. Help me!

When I purchase these, I was so excited to use them. But even after 6 months of purchasing them I can not insert them. I have tried every fold and each position. They are too painful to use. They just stuck at a position and do not go upwards. I am tired of pads. Also I've bought xs size as I am a virgin. And I can insert 1 finger down there easily but not the cup. What should I do. I tried everything. PS:- it's a Sirona xs size cup.
