An actual clitoral piercing is very uncommon. Perhaps you mean a clitoral hood piercing instead?
Hood piercings heal quickly! Mine was not sore after 24 hours, and I felt comfortable having sex within a week, though that was not what my piercer recommended. It is a fun piercing, I love the way it looks, though sometimes it gets annoying and the barbell will rub me raw if I use a vibrator on my clit too long.
