Cup folding

Before actually inserting the cup, it is necessary to fold the cup. There are many different stocks, but not all are suitable for all types of cups
1) The simplest fold is the C-fold In English, it can be found under the name C-fold or heart fold. The cup is taken with both hands, squeezed and folded in half. This fold reminds us of the letter C.
2) The second fold is the Punch down or also known as shell. The cup will form a shell.
3) Seven or triangle-shaped fold Hold the cup with both hands and squeeze the two sides together. Fold one side towards the other to make a triangle or a seven. Depending on which part of the cup you fold.
If you are unable to insert the cup after several attempts, take a break for a while so as not to irritate your mucous membranes unnecessarily. Which can be painful. On the other hand, don't give up on the cup. You can also use a water-based lubricant. For easier insertion, it's better if the cup is wet. Try these stocks and see which works best for you.
