Hello dear..
First of all remove all myths & misconceptions from your mind about masturbation.
In fact, Masturbation is completely normal & doesn't have any bad effect to the body and mind.
Also night emissions are a common thing at your age.

Regarding the problem of premature ejaculation, it's mostly related to anxiety.
So...don't worry about all this & stay relaxed
Avoid stress...practice meditation..this helps in improving concentration & builds up the confidence level.
Have a diet rich in fruits, vegetables, fish, nuts & honey.
Avoid smoking & alcohol.
Despite these measures, if you experience difficulty, it will be better to consult an Urologist to rule out other causes like high blood pressure, blood sugar and other local causes that impair blood flow to your genital organ.
One more thing...avoid consuming any over the counter medication which claim to increase the size of penis or improve performance...it may be harmful.

Wishing you a Healthy Life.
Take care.

Dear patient, semen is a fluid secreted by male gonads (testes) and seminal vesicles located in the pelvis of men. It contains sperms and other chemicals and neutrients required for the survival and viability of sperms and sperms are required for reproduction. This process of semen formation in male reproductive system starts once males reach puberty i.e more than 12 years of age and then continues through out their life and happens under the influence of a harmone called testerone which is also secreted by testes. once semen starts forming in side the male reproductive system and if the male reproductive tract gets filled with it then naturally it has to come out and this generally happens in males during nights associated with sweet dreams and it is called night emession or night fall. If it happens too frequently it simply indicates that it is also produced in high quantity which simply means that the person is either simply more healthy, takes high energy diets or the testerone secretion by his gonads which regulates semen formation is over stimulated probably by indulging into more exotic thoughts and activities .None of these is a medical problem. If a person takes it out with masterbration or once he marries and spends nights with his wife , then henfrequency of night fall automatically becomes less. so you need not to worry about it and there is no medicine to stop this natural process. yes if you were not having night fall by this age and you were not also masterbrating or married then probably some thing was wrong with you. The problem of early ejaculation during masterbration is probably related to the anxiety that you are perceiving by thinking about these issues so seriosly . you can decrease the frequency of night falls to some extent by doing regular exercises, avoiding heavy high energy meals at night and by trying to abstain from exotic thoughts and activities . Regarding the problem of your fore skin , this inability of the foreskin to get retracted is called phimosis ,for this you can show your self to a surgeon who will dilate the hole in the fore skin and the problem will be solved .

Hello ubuntu.hack3
Welcome to HCM

First of all I would like to tell you that masturbation is not at all harmful to health. It is a healthy practice and most of the males or females masturbate. In simple terms it is manual stimulation of genitals to achieve orgasm. So there is no harm in masturbation. Sperm formation is a continuous process and sperms formed in testes are mixed with fluids of seminal vesicles and prostrate to form semen, which is emitted in ejeculation.
Night fall is basically ejeculation that occurs while individual is asleep. During sleep in any normal man, due to fantasy content of dreams erection occurs and a state of orgasm reached and ejeculation occurs. It is also a normal phenomenon, its frequency varies with 1-4 times a month. Chances of nocturnal emission increase when individual don't indulge in sexual activity for long.
During masurbation ejeculation occurs earlier than actual intercourse so there is nothing to worry.
So dear friend don't waste your time in unnecessary thoughts, you are absolutely normal.
Thanks
Take Care
