Dear service user, I can understand your concern about effects of masturbation and penis size. Masturbation in private is a normal and healthy part of sexual enjoyment. Masturbation is akin to sexual intercourse. What penis does in vagina during sexual intercourse, same it does during masturbation in your folded palm. Sexual intercourse is not BAD HABIT, so also the masturbation. It does not cause impotency. Masturbation too can t cause impotency. Masturbation also does not reduce penis size. Lack of understanding makes you feel anxious. Masturbation does not reduce sperm count because semen is manufactured continuously by sex organs. Your concern to increase the size of penis is unrealistic. The size of penis has no relationship with sexual satisfaction of the partner. This is very rampant myth. Another fact is that 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 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. Relax and go ahead. You may consult sex therapist for counseling. No need for any medications. Warm regards.
