What is the difference?
Safeword vs Traffic light system
A safeword and the traffic light system are both ways to pause or stop a scene, so people often ask which to use. The traffic light system is actually a type of safeword arrangement that adds a middle option between "all good" and "stop".
Safeword
A pre-agreed word or signal that immediately pauses or stops a scene, chosen so it cannot be confused with in-character protest.
Full entryTraffic light system
A common safeword convention: 'green' means all good, 'yellow' means slow down or check in, and 'red' means stop now.

In short
Every traffic light system is a safeword arrangement, but not every safeword is a traffic light. The colours add a way to ask for change without ending everything.
What they have in common
Both must be agreed beforehand, can be used by anyone involved, need a non-verbal alternative if someone may not be able to speak, and only work if they are honoured instantly and without guilt or punishment.

- Bacterial vaginosisvsThrushA fishy smell points more towards BV, itching more towards thrush, but symptoms overlap, so it is worth getting them checked by a pharmacist, doctor or sexual health clinic.
