GIRLS ONLY! Pls back me! Its far-reaching!?

I have my term and its really dry! Luckily! Im 13 and I ussually wear pads. the darkness ones though because they are more comfy.I am really not liking the model of asking somebody who knows me so i'll ask here.I own never seen a tampon b4 and I know some girls stir in the the deep when they are having time because they are wearing tampons.My MALE cousin challenged me to own a swimming race within the swimming pool. Pls tell me what is the difference between pad and tampons because im sooo in-experienced! Dont tell me to skip the defy tell me the answer and wether it can work. Tampons shift inside your vagina to absorb the blood. You can rob them out by pulling a sting that hangs out side the vagina. You can swim beside these. It looks like a short white tube beside a sting on one end. You can't see the actual tampon when the applicator is on it though. When you appropriate it out it may have expand some, but to be precise because of the blood absorbency. When you buy the tampons, there should be a treatise with instuctions on how to use them.
Pads are placed surrounded by your underwear, tampons are inserted into your vagina. If you use them you can race surrounded by the swimming pool, if you don't want to use them, tell your cousin they enjoy to wait till subsequent week!
