If you're talking about people who aren't addicted then it's an aveiro like any other (kind of). Every living person has his/her own YH and needs to fight it when it comes to it.
Addicts on the other hand have to learn how to live on a daily basis, no matter what.

I completely agree with you, however, it's not black and white. There is a gray area between being an addict to lust and having the nisayon equal to a nisayon to eat treif. What I mean is that this is a nisayon that one may not be addicted to, however they still struggle with it a lot more than a standard aveirah. So that person would have to confront it on his level with the tools that work for him In a personal way
