Can I sell my staked ETH?

I'm really curious about this. Could you please explain something to me? I've been staking my ETH for quite some time now, and I'm wondering if it's possible to sell it. Is there a process or certain steps I need to follow? I'm not entirely sure how the staking mechanism works, and I don't want to make any mistakes that could potentially cost me. Could you shed some light on this matter for me? I'd really appreciate it if you could guide me through the selling process, if it's indeed doable. Thank you so much in advance for your help!
