How to find Monero address?

How do I locate my Monero address? I'm having a bit of trouble navigating through the cryptosphere and I'm not sure where to start. Is there a specific section in the wallet interface where I can find it? Or do I need to generate a new one? Also, is there any security measure I should take when sharing my Monero address with others? I want to make sure I'm doing this safely. Please, could you provide a step-by-step guide or any relevant tips? I'd greatly appreciate it.
