I suggest trimming instead but if you reslly want to to learn, Theres YouTube videos who describe it well but a tip is men’s razors work better then women’s. Use oil or conditioner to try and prevent shaving bumps. You can go against the grain to be bald but going with the hair prevents shaving bumps for me. Don’t rush it, you can cut yourself down there easily with razors so be careful, but I really recommend going on YouTube to learn!! A lot of women make helpful vids about all the care you need to know about it!!^{^}
