Off the top of my head -- Most of my questions had to do with tampons. I always wondered when you know you're "ready" to use them, and the truth is, it's really up to you. Some people start their first period, some years after. If you dislike pads, try tampons. If it doesn't work for you, just switch back to pads and wait a little why until trying again.
Also -- there's the really common question of if you're still a virgin when you use tampons. The answer is, of course! You're still a virgin until you actual experience sexual intercourse. While it's true that a tampon can break your hymen a bit, that'll just make losing your virginity less painful.
Remember, you can't go swimming with pads, or get them wet at all.
With tampons, you can go swimming, go to the bathroom... just about everything.
One last thing that is commonly wondered is no, they can't get lost in your body -- and they also can't get stuck in there, either.
Hope this helped you out a little bit! This is just a few of the things I remember wondering when I started. Feel free to PM me if you need any more help. :)
