Vibrators are made to increase pleasure. Everyone's experience will be slightly different, but the goal is maximum enjoyment. While some sex toys are made with a mixture of pain and pleasure in mind (for example, sex toys for BDSM), it shouldn't hurt to use vibrators for clitoral stimulation or penetration. (remember to use lubricant). If using a vibrator hurts you, consult your doctor as it may indicate a larger health problem. Using vibrators can only bring you happiness and more intense orgasms. It's a tough feeling to describe, it will definitely make you feel good to try.
