What does that disability mean? whether physical or sexual, I mean whether he is not able to perform intercourse and foreplay effectively or they have any psycological illness or impotence. Another disability is the lack of interest and lost sexual desire. Those who are mentally ill can never perform sexual act effectively. 

Well in all the cases, if man is disabled, there would be difficulty in performing sexual act and the partner either husband or wife will not get satisfaction from it. We have seen alot of people in the clinics who have complained of having such types of problems and inability to perform sexual act enthusiastically.

Sex education would be the most appropriate mode of treatment for such cases. Regular visit to the sexulogist or psychiatrist brings changes in their sexual behaviour and improvement in their performances. As for as religiously, Any man or woman should have full rights to have sex with husband or wife with full emotions and invovments. Islam would never prohibit any person to get sex education to improve his performance and for treatment of his or her disability.
