What does it mean if my labia area have a slight burning/tingling sensation when receiving oral?

The way that form...: of stimulation by that person happens to be perceived by your sensory nerves being stimulated is burning/tingling. It may depend whether you're talking about direct clitoral stimulation causing that feeling vs. a more generalized stimulation throughout the vaginal area not necessarily just by the clitoras. If the sensation is unpleasant you may wish to speak to your partner & figure it out.
