Doctor of Medicine
As long as the coitus, erection, ejacualation, masterbation, norcternal ejaculation, are concern I could say that it is great myth are there taking all of these topics because I frequently answers such queries, it is all the disease to most of the persons those are worried about this, what comes before that still many of such persons does not know what is the reproductive sytem and how it functions, many person does not know the biological fact for all of these topics
Coitus:- It may cause HIV infection, It may cause some STD, fear of pregnancy cant satify the partner, it is over too ealry
Erection:- Does not have strong erection, it becoms loose too early, looking for medicines for this trying some non pharmaceutical agents and wasting money
Ejaculation:- premature ejaculation asking for medicine for this, have great fear and due to this some avoids coitus
Masturbation:- It is very bad kind of sin, may cause several disese makes you weak you would be no more man, makes your vein so weak that you wont be able to satify your wife and you wont be father, and what not
Nocterl Ejaculation: It is a kind of disease that consumed great energy that you wont be able to wake up in the morning caues bad bacache, may be danger in later life
Let me tell something all of these myths are very dangerous and it is not logic scientifically, it could cause depression and anxiety nervouse break down, loss of self confident, it is all physiological phenomenon and natural instict, like others as for example, sleep, hunger, thrust, defication, voiding, just difference is, it is the social barrier and desency required for sex one need to follow the rules and regulation to maintain and secure the society.
