This tag is for situation where someone is using one of their organs to stimulate an organ of a character of ambiguous gender.
The other person can also be using an object.
Licking its anus, pinching its nipples, putting their penis in its mouth; the ambiguous character is the one whom is on the receiving end.
'Using' does not necessarily assume consent or dominance, so this is not appropriate for a dominant ambiguous character having anal sex with a male because she is still receiving his penis, even if it is using force.
To determine who is the giver and who is the receiver try to think who has the 'passive' part and who has the 'active' part.
An odd exception to this is penetrable_sex_toy, as a person can put this in their hand and 'use' it on someone else with much more control than the person it is being used on. What if we know it's a ambiguous character who has been turned into another gender OR whose gender has been revealed?
