Capsaicin produces warmth by activating heat-and-pain receptors directly. On mucosal tissue that is a poorly controlled dose of an irritant, the effect cannot be rinsed off quickly, and it can be intensely painful on any tissue that is already inflamed or torn.
Look for instead: A plain lubricant; warmth from friction is not a formula problem to solve.

Does the specific product still matter?
Yes. An ingredient list shows what is in a formula, never how much, and two products sharing an ingredient can behave completely differently. The product's own label and instructions always take priority over a general category rating.
