It is very distressing to hear what you are going through. It is clear that he has a high sex libido and you are doing your best to please him sexually. It is never easy for a young girl, who is just married to do the house work the whole day and then try to please her husband the whole night.
Why do you think that just because he has married you, it is his right to have sex whenever, he wants. You are well within your rights to say NO, when you are not in the mood. Unfortunately, unless you have some support from your Family, this may be difficult to achieve.
But, what is absolutely not acceptable is for him to beat you physically. Have you spoken to your Family about the ill treatment? What is their opinion on this? You will have to be firm on this issue. Speak to an Elder in your Family or a Religious Group. Unfortunately, they may not be too supportive.
You have to take some action. Take the help of your local NGO. There are many Political Women’s Organizations, that will be willing to have a word with your Husband.
Threaten to go to the Police. Do something about it. Take photos of the violent marks left on your body. The more you take this nonsense, the more it will continue. It generally gets worse, if you do not raise your voice. It may be your private life, but when there is violence, it is no longer a private matter.
He may threaten you, but believe me, one visit to the Police Station and they will take off his pants. He will not dare to even speak to you roughly. But you have to help yourself. No one else can help you.
We hope that things will work out.
