If I believed that homosexual acts are not learned/learnable, and that same-sex attraction was not learnable and not reversible; and if I believed that homosexual men were generally able to be monogamous, I might give your suggestion some thought as a matter of cultural adoption, Catholic teaching aside.

But I genuinely believe that all people are capable of forming deeply loving, opposite-sex relationships and that our culture should encourage those types of relationships exclusively.  As my Mom used to say, "Everyone has their match."  People overemphasize sex and under-emphasize the importance of of love and children in this life.  Indeed, many don't even know what love is.
