I find the Catholic Church's description that "SSA is disordered" a very good expression. Just like if someone was born blind, or born with some cardiac defect, those things can occur naturally, and are disordered states. Disordered means "ordered to a wrong end".
Saying that "SSA is inherently wrong" is not incorrect, either, but people tend to easily misunderstand this expression. SSA is wrong in the sense that the attraction is wrong, disordered, unhealthy, but not in the sense that the person deliberately chose to do something wrong. It's not the person who is wrong, but the attraction he/she is experiencing.
If I experienced attraction to my neighbor's wife, that would also be "disordered", even "wrong" in the sense that the attraction was wrong. However, I as a person did nothing wrong if I fought this attraction and chose not to act on it. It is quite laudable to fight any disordered attractions we may feel.
Our brothers and sisters who experience SSA are not alone in society, even if that particular kind of disordered attraction is less common than some others. Virtually 100% of people experience some form of disordered sexual urge and/or attraction during their lives. Some feel like watching pornography (especially men), others feel like dressing immodestly (especially women), yet others feel like having pre-marital sex, sleeping with someone else's spouse, with someone of their own gender, with a family member (incest), copulating with animals, feel the urge to masturbate, etc. These are all disordered urges and attractions, and we all have to control ourselves, not to act on disordered urges and attractions.
