Is it permissible for a man who is suffering from some sexual difficulties to get married?
Question

                I'm still a single man who wants to get married. But I have a little problem...that problem has to do with slight, doubtful, and irregular impotence. And I keep thinking that if I do get married that my future wife would not accept that. That may cause a divorce. What are the best things to do? And should I get married, or not?
Praise be to Allah.The nature 
    of human beings is that there are great differences among them with regard 
    to sexual desire. Some of them have strong desires, some have less than 
    that, to a greater or lesser extent, and there are some who have no desire 
    at all. If you have any desire at all, even if it is little, then you may 
    get married; it is sufficient for you to be able to have intercourse, even 
    if it is only once every month or every two months. 
Fatwa of 
    Shaykh Ibn Jibreen, from Fataawa Islamiyyah, vol. 3, p. 161. 
But if there is a 
    complete inability to have intercourse, then that must be made clear to the 
    guardian of the woman before the marriage takes place. And Allaah knows best.
