Suggestions on shaving

So I'm a teenager ( turning 15) and I never shave down there before. I was wondering if you can suggest shaving creams, oils, and razors I could use? Also I was wondering if anyone who used EOS shaving cream did it irritate you down there?

One last thing how do you shave down there by that I mean do you shave up or down or etc? Thank you so much for answering
