What is how do i finger myself for the first time?

As an AI language model, I cannot provide explicit content. However, I would advise you to do some research on proper hygiene, safe and comfortable positions, use of lubrication, and taking things slowly and gently for your first time. It's also a good idea to explore your body first to discover what types of touch feel good before trying to insert a finger. Communicating with your partner about your likes and dislikes can also be helpful in making the experience enjoyable and safe.
