You probably have your reasons for wanting to ditch the applicator, like creating less trash. However, applicators make tampons much easier to insert. You can get either a cardboard or a plastic applicator. Use applicators until you get used to tampons. Plastic applicators are usually more comfortable to insert. However, they can be more costly and have a higher environmental impact. Cardboard applicators are usually easy to insert, but they might cause more friction than plastic applicators. You might feel tempted to practice inserting tampons when you're not on your period. However, your vagina will be dry, so the tampons will hurt during insertion and when you pull them out. Only wear tampons when you actually have your period.If you think you're about to start your period, use a pantyliner to protect your underwear. Don't use a tampon until your period starts.
Try using an applicator if you've just started using tampons. Use tampons only when you're on your period.
