There is (1) Basic Principle of Morality:

"Love works no ill towards a neighbor"

Any mindset to violate that principle is defined as: immoral.

Glaring Conclusion: Since the vast majority of Sexually Transmitted Diseases among people involve anal vectors; -- Plus the gamut of research that clearly shows numerous complications of both physical & psychological nature in regard to people who participate in the fetish of AnalSex; -- The practice of anal penetration as a sexual fetish violates the Basic Principle above, & is therefore: immoral.

Corollary: People who promote practices that are destructive (immoral), - are themselves: immoral persons (appealing to fraud & callous disregard as their fundamental philosophy of self governance). 

Being a guy who loves guys is not a choice - nor does love lend itself to ill; But willfully engaging in anal-sex fetishes, is a choice, -- one most dangerous.

If the shoe fits wear it.  If not, don't force it...

G0YS: More than just a name:

Despite the flood of e-mails affirming that this website has hit the mark with many men, there are some critics (mostly of the ButtFuckTyranny genre), who question the fact that G0YS are different from gAy. Despite the fact that the feedback makes the point clearly, we want to take this space & stress that G0YS are as different from gAys, as wheat is from tares (weeds), Furthermore, most G0YS have a deep seated belief that there will come a day where the (2) are distinguished for the acts performed in their tenure among men.  The wheat will be gathered & stored, but the tares will be bundled & burned. So, in the most literal sense of the terms: Despite the fact that they indeed love men, G0YS are N0T 'Fags'.

Does MORALITY Ultimately Matter?

Since you'll be dead much longer than you'll be alive, a very important question arises:
Which side of the line matters more?

Actually ... that's a trick question.  Everybody believes the infinity side matters more.
The difference is that one philosophy will take steps to prepare for it responsibly; -- While others will pretend it is of no consequence...

What do you suppose the cost of being wrong is?

If Christianity is to receive a rejuvenation it must be by other means than any now being used. If the to recover from the injuries she suffered, there must appear a new type of preacher. The proper, ruler-of-the-synagogue type will never do. Neither will the priestly type of man who carries out his duties, takes his pay and asks no questions, nor the smooth-talking pastoral type who knows how to make the Christian religion acceptable to everyone. All these have been tried and found wanting. Another kind of religious leader must arise among us. He must be of the old prophet type, a man who has seen visions of God and has heard a voice from the Throne. When he comes (and I pray God there will not be one but many) he will stand in flat contradiction to everything our smirking, smooth civilization holds dear. He will contradict, denounce and protest in the name of God and will earn the hatred and opposition of a large segment of Christendom.
