Dear service user, Thank you for contacting Healthcaremagic. I have gone through your question and understand your concerns. I want to convey scientific facts to you which will help you. 1. 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! You remember that what is important is strength and not the length! 2 and 3. Premature ejaculation can be treated successfully by behavior therapy with medicines like Depoxetine or Paroxetine. 4. Consistency of semen depends on upon factors like period of sexual abstinence, age and intensity of sexual stimulation. Color, consistency and quantity has nothing to do with virility or sexual satisfaction of an individual. Neither do they have any relation to the partner s satisfaction. 6. See dermatologist if you have complaint of persistent and recurrent hair fall. 7. Its normal to have pre ejaculate fluid to come at the time of sexual arousal. 8. You are worried and anxious just because of lack of sexual knowledge. I suggest psychological counseling. Do not let lack of knowledge ruin your mental stability. I hope this will help you. Wish you happy sexual life ahead.
