I have observed this in one gay couple where the desire was in least one of the partners who I knew personally. If it happened in one it is likely that it happens in others though I don’t think anyone would say it is commonplace.
I have also observed the unitive nature of homosexuality in several gay couples that due to age or infirmary no longer have genital sex. By unitive I mean the love that keeps them together in a supportive loving relationship. This term is used by religious ethicists.
I am sure that though some sophisticated reasoning some in the CC will say that unitive love is not love. Who am I to argue with them?
It doesn’t really require ‘sophisticated reasoning’ to see that there is no special merit in same sex unions that mimic the union between man and woman. With honest observation of life and nature, it is clear. I use the term ‘special’ here in its pure sense from its Latin roots
species. When something has special merit… it denotes its role in species survival or the good of the species as a whole. The sexual intercourse between men and women has as its end procreative merit and in service of that, unitive merit.
The social intercourse of friendship between people is a special relationship that facilitates the blossoming of charity. It ‘represents a great good for all’ the species.
**CCC 2347 **The virtue of chastity blossoms in friendship. It shows the disciple how to follow and imitate him who has chosen us as his friends (Cf. Jn 15:15), who has given himself totally to us and allows us to participate in his divine estate. Chastity is a promise of immortality.
Chastity is expressed notably in friendship with one’s neighbor. Whether it develops between persons of the same or opposite sex, friendship represents a great good for all. It leads to spiritual communion.
From the ‘Introduction to the Devout Life’, St Francis de Sales famed treatise (highly regarded by both Catholics and Protestants), friendship is specially treated of for its place in growing towards godliness. Here he distinguishes between the cloistered religious person, who has no special need for individual friendship, and the ordinary person for whom good friendship is necessary.
Just as men traversing a plain have no need to hold one another up, as they have who are amid slippery mountain paths, so religious do not need the stay of individual
friendships; but those who are living in the world require such for strength and comfort amid the difficulties which beset them. In the world all have not one aim, one mind, and therefore we must take to us congenial friends, nor is there any undue partiality in such attachments, which are but as the separation of good from evil, the sheep from the goats, the bee from the drone—a necessary separation.
What need to affirm so unquestionable a fact! S. Jerome, S. Augustine, S. Gregory, S. Bernard, and all the most notable servants of God, have had special friendships, which in nowise hindered their perfection. S. Paul, in describing evil men, says that they were “without natural affection,” Rom. i. 31. i.e. without friendship. And S. Thomas, in common with other philosophers, acknowledges that friendship is a virtue, and he certainly means individual friendships, because he says that we cannot bestow perfect friendship on many persons. So we see that the highest grace does not lie in being without friendships, but in having none which are not good, holy and true.
For friendship to be true, it does not form its attachment with undue partiality to what does not belong to it. The coupling of a ‘sheep and goat’ or ‘the bee and drone’ negate friendship. They can’t have any unitive merit. It’s like trying to join both good and evil to make something out of it. It’s impossible. Not unitive.
The relationship trying to be established here, amounts to the joining of a good with evil. Even when you say you know of gay couples who don’t have sex due to age or infirmity, the requirement for sexual fidelity betrays its nature as imitation marital, just as certain married couples remain married when sex is absent due to age or infirmity.
