If you experience pain during prostate stimulation, don't worry – it's normal, especially for beginners. Discomfort can occur due to tension or nervousness, inadequate lubrication, or improper positioning of the massager. Take a break, relax, and try to identify the cause of the discomfort. Ensure you are using plenty of water-based lubricants, and consider adjusting the angle or pressure of the massager. If pain persists, stop using the toy and try again another time or consider seeking advice from a healthcare professional.
