Next, you're 13-years-old. You may not like it but I think you ought to wait until you're much older for this. Really, you're no cleaner without it than you are. Also, most people do this for sexual reasons to appeal to partners. At your age you shouldn't even be thinking that.
If it's about the appearance that's fine but it's very easy screw this up if you don't know what you are doing and get razor burn. I wouldn't do it. Perhaps, if you know an older female you can trust to talk about it (embarrassing but it could help) and learn that it's not something to do yet that may help.
