I would appreciate if you could provide more details about yourself like age, relationship status, sexual history because these things are common during adolescence. Anyhow i have the following suggestions for you. Premature ejaculation and nocturnal emission are common complaints are often caused by anxiety and too much stimulation. Other psychological factors may also be involved. The conditions usually improves without treatment. Premature ejaculation: Practice and relaxation should help you deal with the problem. Some men try to distract themselves by thinking nonsexual thoughts to avoid getting excited too fast. There are several helpful techniques you can try. The stop and start method: This technique involves sexually stimulating the penis until you feel like you are about to reach orgasm. Stop the stimulation for about 30 seconds and then start it again. Repeat this pattern until you want to ejaculate. The last time, continue stimulation until you reach orgasm. The squeeze method: This technique involves sexually stimulating the penis until you are about to ejaculate. At that point, you gently squeeze the end of the penis (where the glans meets the shaft) for several seconds. Stop sexual stimulation for about 30 seconds, and then start it again. You may repeat this pattern until you want to ejaculate. The last time, continue stimulation until you reach orgasm. Antidepressants such as Prozac and other selective serotonin reuptake inhibitors (SSRIs) may be helpful because one of their side effects is to prolong the time it takes to reach ejaculation. You can apply a local anesthetic cream to the penis to reduce stimulation. Decreased feeling in the penis may delay ejaculation. Condom use may also have this effect for some men. If these distraction techniques cause difficulty maintaining an erection, medications used for erectile dysfunction may help. Nocturnal emission:(semen getting released at night/night falls/ wet dreams); The reason for nocturnal emissions is that the body of a male is partly designed for involuntary ejaculation since a male need to ejaculate reproductive fluids from time to time. The most common reason for nocturnal emissions is romantic dream imagery. Furthermore, when a male gets too much involved in the thoughts of lovemaking, the amount of testosterone increases that stimulates the production reproductive fluids. And, the reproductive fluids get ejaculated through involuntary ejaculation process when the reproductive organs are unable to hold the excess amount of fluids. I would recommend you to avoid over-stimulation of your genitals, you should take the initiative to self-control, avoid reading an adult magazine, TV, pornographic websites, and try to make efforts to overcome the habits of sexual fantasies. Try to involve your spare time in sports, meeting friends, actively participate in cultural and other activities. all these efforts will help divert your attention from the sexual fantasies and this reduce the frequency of night falls/ wet dreams Evaluation by a sex therapist, psychologist, or psychiatrist may help in both cases.
