This is a quote from the 1973 us catholic bishops document(Principles to Guide Confessors in Questions of Homosexuality):
A homosexual can have an abiding relationship with another homosexual without genital sexual expression. Indeed, the deeper need of any human is for friendship rather than genital sexual expression … If a homosexual person has progressed under the direction of a confessor, but in the effort to develop a stable relationship with a given person has occasionally fallen into a sin of impurity, he should be absolved and instructed to take measures to avoid the elements which lead to sin without breaking off a friendship which has helped him grow as a person. If the relationship, however, has reached a stage where the homosexual person is not able to avoid overt actions, he should be admonished to break off the relationship.
now granted, this is pretty old, but its pretty interesting.
