How to Shave Pubic Hairs Perfectly? (for a beginner)

Hi everyone, I’m a total beginner to grooming and I need some step-by-step help. I want a completely clean, bare shave, which I know means I have to use a razor since a trimmer doesn't get it fully smooth. However, my past attempts have been disastrous. I’ve tried both a razor and a trimmer, and both times I ended up with cuts and bleeding.

I have a few specific questions and would appreciate any advice:

• The Routine: What exactly do I need to apply before using a razor? What about after I shave to prevent razor burn and bumps?
• The Razor: What kind of razor works best for sensitive areas?
• The Trimmer: I’ve been using the exact same electric trimmer for my pubic hair as I do for my beard. Is this normal, or should I be using different trimmers for different body parts?
• Avoiding Cuts: How do I hold the skin and maneuver the razor properly so I don't get cuts or snag the skin?

If you could share your exact routine, product recommendations (budget friendly), or any beginner tips to avoid bleeding, I’d be really grateful!
