First time shaving vagina 😬😨🐱

Hello beauties! I need help,

This is my first time I'm considering to start shaving my pubic hair. Some people recommend me to start trimming and not shaving for the first time, so my skin gets used to (I have really a sensitive skin). I know there are better options like laser or waxing but I'm broke for the moment lol. What are your tips for someone starting in shaving? Should I just trim and how should I do it? I also have seen especial electric razors for down there, those works? And what is the aftercare thank you!!!! 😊
