Managing the appetites requires self-denial. In the case of married couples, the spouse has a moral obligation to satisfy the other sexually within moral and reasonable limits (i.e., sexual abuse or objectification of the other is never admissible).
Phone addiction is in this sense easier. It can also be managed through abstinence or even eliminated cold turkey if you wish because we have no intrinsic desire for phone use, but we do have an intrinsic desire for sex.
And yeah, the passions, when we are ruled by them instead of ruling over them, can darken our minds and enslave us. (In your example, the "daughters of lust" are apropos.) A man has as many masters as he has vices.
