Does Shivling mean private part?

Excuse me, but I've come across the term "Shivling" and I'm wondering if it's being used in a specific, perhaps cultural or religious context that I'm not aware of. Could you clarify whether "Shivling" is indeed referring to a private part, or if it holds a different meaning altogether? I'm genuinely curious to understand the nuances behind this term and how it's employed in various contexts. Thank you for your insight.
