On the other hand, you have to be willing for a willing effect to effect you. And if you are willing, you don't get a saving throw.
Most spells that affect 'one willing creature' don't allow a saving throw. If you're willing, it works; if you're unwilling, you're an invalid target.
This is completely different to voluntarily failing a will save.
In particular, unconscious creatures are automatically considered willing. An unconscious creature is a valid target for Levitate (Target: one willing creature), but he does not automatically forfeit his save against Inflict Light Wounds (Saving Throw: Will Negates).
If I drink a Potion of Cure Light Wounds, and state "I wish to make a save", I get to make a Will save. If I make no statement of intent, then I don't attempt the save; the spell is 'Will negates (harmless)'.
If I drink a Potion of Inflict Light Wounds, and state "I wish to forfeit the save", I don't attempt the save. If I make no statement of intent, then I attempt the save; the spell is 'Will negates'.
If I drink an unknown potion, and make no statement of intent, then if the spell is Will negates (harmless), I don't attempt a save; if it's Will negates, I do.
The default for spells is that a saving throw is made, unless the creature elects to forfeit the saving throw. However, for (Harmless) spells, the default is that no saving throw is made, but the creature can elect to attempt a saving throw.
In the absence of a conscious decision either way, the default applies.
