Quran: Al Araaf (189) It is he who created you from a single soul and from him, created is mate, so that they may seek peace and tranquility from each other.
Then, when he embraces her she gets pregnant with a miniscute burden.
Sex activity is an important factor in the married life without which, the marriage fails. Success of marriage depends on the successful sex life of the couple.
Usually, if the girl is innocent, she will be shocked to find the advances of the bridegroom on the first night. Sometimes she may hate the man who forces into her. Hence it is better, someone in the girl's family intimate to her what is going to take place and it is normal in marriage and natural. The above Ayath of Quran will explain the process. It is due to this that the children are born. This way she will be prepared for the event and will not be shocked. Otherwise, I have seen instances, the bride came out of the room shouting that the man is doing shameful things. If the bride does not allow the groom to come near her, there could be suspicion that the girl is not ready for marriage or she has any other affair in other man. Sometimes, due to late marriages or by other factors, the vaginal passage may be blocked or closed. If the groom cannot penetrate, he will get frustrated. He may think that the bride is not cooperating. The marriage can break. Air because, they don't know the cause of the problem. If they take the help of a doctor, with a small procedure, a small cut, the problem will be solved.
There are many such instances. It is a simple treatment. The other side, the bridegroom may not be successful in his attempt on the first night. The other women in the family will be checking the success next day, by examining the inner wears of the bride. Due to this tension, the bridegroom will have anxiety to perform. That itself will fail his attempts. Some grooms take weeks or some months to succeed. They should be allowed to take their own time. The families should not interfere in this.
Even if there is a problem with the bridegroom for not performing due to erectile dysfunctioning, it can be solved by the doctors. It should not be the case for concern.
After marriage, the wife shall never refuse or postpone or refuse the demand from her husband for sex. It is a sin. The angels curse her as long as she stays away from the husband (Hadees). It is a physical urge of the husband. She has to satisfy him. It is his right in the married life. All that tension that had built between the husband and wife relationship, with one round of sex it will melt away. That is why, quran says the union of male and female gives peace and tranquility. If the wife refuses the demand of her husband, lots of tensions and problems will build up. Of course, during her monthly periods, she can refuse giving the reason. In the physical build up of the man, the spermatozoa is created and collected in the scortom-testicles. The men get sexy feelings. Either they are released in his wet dreams in his sleep or by sex activity with a female. This way, the wife have to help him to release his tension. If the wife regularly attends to this urge, the husband will be very much attached to her.
