Dear user, Thank you for contacting Healthcaremagic. I can understand your concern about penile size for sexual satisfaction of the partner. Your concern to increase the size of penis is unrealistic. Wider and longer penis gives more satisfaction to partner is a myth. Unfortunately, this thing is shown dramatically in pornography. This spreads the myth more. The 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, lower one and half inch part of vagina. So for female sexual gratification, the size of erect penis could be anything from two inches or more! You remember that what important is strength and not the length! Penis entry through vaginal opening followed by to and fro continuous movements is adequate. It is men s technique, not his penis size that characterizes the lover in him. The size of penis has no relationship with sexual satisfaction of the partner. There is no scientifically proven medicine for increasing penis size. There is no need of such medicines at all ;-) You may have counseling with your psychiatrist or sex therapist. Wish you good health.
