Thank you very much for your kind help.
Praise be to Allah.Homosexuality in Malaysia
We do not have any information about homosexuality in Malaysia, but we assume that the Muslims there feel total abhorrence towards this shameful act, because their religion, Islam, emphatically forbids this deed and prescribes a severe punishment for it, in this world and the next. 
How could it be otherwise, when the Prophet of Islam (peace and blessings of Allah be upon him) said: "Whoever you find committing the sin of the people of Lut (Lot), kill them, both the one who does it and the one to whom it is done" - i.e. if it is done with consent. (This hadith was narrated by al-Tirmidhi in his Sunan, 1376)
Punishment for homosexuality 
The scholars of Islam, such as Malik, al-Shafi'i, Ahmad and Ishaq said that (the person guilty of this crime ) should be stoned, whether he is married or unmarried.
Is homosexuality a sin?
There is no doubt that homosexuality , which goes against the pure human nature created by Allah, by making men content with men and women with women, destroying families, adversely affecting the birth rate, causing the spread of killer diseases, harming the innocent when children are raped, and generally spreading corruption on earth, should be uprooted and stamped out.
Perhaps your research will lead you to find out much more about this religion with its great laws and accurate rules and the wisdom of the One Who revealed it.
We ask Allah to grant you help and success, for Allah is the One Who guides to the Straight Path.
And Allah knows best.
