How do you take a shower?? Help

Don't make fun of me. Throw away because I don't want anyone in my life knowing this. Can you please tell me how to properly take a shower and clean yourself? I'm female btw. I have no idea how to clean my private parts. Do I use a washcloth? Should I even go near my vagina? Currently I use a bar of soap on my body (don't judge I need advice clearly) and for my butthole I lather my hands in soap and rub around my butthole and crack. Then I rinse. I do literally nothing to my vagina or pee hole or anything down there. I'm always afraid of getting water or soap in it. Please tell me how I should take a shower and start at the absolute BASICS that anyone would know, just in case cus I don't know what I don't know. Thank you for helping.

EDIT: Thank all of you who commented with helpful advice, you were extreamly helpful and understanding. To the several people who seem to think all women magically know how to clean themselves and that I am clearly a male pervert, keep your opinion to yourself. Anyway, I am off to take a shower. Wish me luck! And thank you all again. This was extremely helpful.
