Thanks for this inquiry to our TruthBook site. And, we've been asked it before, so I am going to give you some links further on in the reply, so you can peruse previous replies.
But in the short term, I can tell you that The Urantia Book does not specifically address the topic of homosexuality. There is a good deal of instruction about the "mating instinct," and some passages about friendship between two people of the same sex. But there is no declaration that sex between two same-sex people is right or wrong; only that it is beneficial for all people to harness this powerful sex urge into channels of ethics and self-control:
82:1.10 No human emotion or impulse, when unbridled and overindulged, can produce so much harm and sorrow as this powerful sex urge. Intelligent submission of this impulse to the regulations of society is the supreme test of the actuality of any civilization. Self-control, more and more self-control, is the ever-increasing demand of advancing mankind. Secrecy, insincerity, and hypocrisy may obscure sex problems, but they do not provide solutions, nor do they advance ethics.
83:0.3 It is because of the sex urge that selfish man is lured into making something better than an animal out of himself. The self-regarding and self-gratifying sex relationship entails the certain consequences of self-denial and insures the assumption of altruistic duties and numerous race-benefiting home responsibilities. Herein has sex been the unrecognized and unsuspected civilizer of the savage; for this same sex impulse automatically and unerringly compels man to think and eventually leads him to love.
That being said, you should know that Urantia Book teachings about sex, mating, and marriage are overwhelmingly favored on the side of the man/woman relationship – that relationship being the one that can produce children, and that can act as the cement that solidifies the home in which to raise them.
These days, homosexual couples are also creating marriages, homes and safe havens for children – and this is a feature of our modern civilization that is in the forefront of our newspapers at times. But, this kind of situation is not specifically addressed in the teachings.
Nonetheless, it seems to me that a good rule of thumb in ANY relationship is the practice of friendship, devotion, selflessness, tolerance, and most of all, love.
