It’s not wrong to have homosexual inclinations; it’s only wrong to act upon those inclinations.
Some people have overcome homosexual inclinations, and go straight. If he tries, and can’t do that, he can live his life as a happy single person. He can find a job he loves, do charitable work, etc., just like heterosexuals do.
No, it's not is sin. But the mere inclination is "instrisically disordered".
