Dear user, Thanks for writing to HCM. I understand your concerns regarding night emissions. This happens to many youngsters or even at later stage of life when one is not sexually active (masturbation or intercourse) or having relatively long abstinence. Semen is being manufactured by genital organs continuously; it has to be expelled by some means. This situation is just akin to a glass of full water to which you add more water, with the logical result that it overflows! This happens to semen too. If one neither has sex nor masturbation for long time, semen gets expelled in the form of night emissions, which is normal. This is not an illness or disease. No need to consult doctor for this. When one engages in regular sexual activity with partner or masturbation, the night emissions will be decreased or disappear. Hope I have answered your question. If you have any further questions I will be happy to help. Wish you good health. Size of erect penis more than one and half inch is enough to have sexual gratification for the partner because only outer part of vagina is sensitive. Inner vagina is largely insensitive. ‘Bigger is better’ logic is a myth. Wish you good health.
