Wherever you begin, begin light and slow. 'Light' isn't a tribute to her fragility — it's calibration: pressure is much easier to increase in response to her feedback than to walk back from too much, and touch sensitivity varies enormously between people. The often-taught outside-in order — outer areas first, more direct contact later — is one reasonable low-stakes starting sequence, not a mandatory script. Skip it or reorder it if her preference is direct contact from the start.
Before any landing on the clitoris itself, there are several flavors of approach — none of them a required stage, and all of them skippable. One is broad, outside-in contact. Another is hovering: in place and aligned, but not landing — warm breath, the tip of your nose, or a single lip grazing past. A third is barely-there circles around the clitoris rather than on it. Treat them as options, not a ladder: try one, watch the response, keep what works, drop what doesn't.
Hovering in particular divides people — it's one option among equals, not a superior opening. If it isn't landing for her, that's information, not a failure: slow down, or make it a question — 'Closer, or no?' — and return to whatever was working.
Use a broad, flat tongue surface rather than a pointed tip at first, and let lips, chin, and the flat of your nose share the contact. Try one small thing, watch and listen, then adjust one variable — pressure, speed, or place — never all three at once.
