hi..thanks for writing..i have understood your concerns..
masturbation is natural habit and more than 90% of men practice it..it is not a bad habit and it does not cause any sexual and physical weakness..
it is the way of satisfying your sexual needs in the absence of partner..
you shud not think that because of the masturbation you are facing sexual weakness, otherwise it will become a psychological play in which you will get more and more
depression and after that your sexual activities will get compromised though you do not have any weakness..
our body has sexual gland which produce and store semen and the storage capacity is limited..so when you masturbate regularly the storage is made empty regularly so there are no wet dreams but when you stop masturbating then your storage will become full and then it will overflow and come out in dreams when there is erection, in passage of urine and stool when there is increase in abdominal pressure..
so continue doing masturbation, you wont have wet dreams...
do not believe myths about masturbation, penis size and sexual weakness prevalent in the community..
your
anxiety and worry regarding this issue is making you depressed and thats why you have trouble concentrating in you work and studies..
you can also
consult a psychiatrist and take professional help..
i hope this advice will be helpful to you..best of luck..
