Dear service user, Thank you for contacting Healthcaremagic. I have gone through your question and understand your concerns. The width and length of penis vary from one individual to another. The normal length of vagina is about six inches. Only outer one third and the front wall of vagina have nerve fibers and hence sensitive to stimulation. Rest of inner two third is largely insensitive. So if you want to arouse your partner during sex, you should focus on the areas of maximum nerve endings hence clitoris and inner lips or labia minora, the outer wall and outer two third of vagina. So for female sexual gratification, the size of erect penis could be anything from two inches or more! Your is 9, no need to worry. Your unrealistic expectations and beliefs causes you feeling misery. You remember that what is important is strength and not the length! Entry and to and fro continuous movements are adequate. It is men s technique, not his penis size that characterizes the lover in him. Bigger is better is Godzilla logic. Hope, I have answered your question. If you have any further questions I will be happy to help. Wish you good health.
