Here’s what I would advise you, however:
1. Don’t ask boys out. Don’t be the aggressor. I know you’re a sexually charged teenager, but you have to value yourself as a woman. And you’re not too young to understand that men (even young men) feel really good about themselves and their girlfriends (you?) when they’ve won the woman over. If you throw yourself at these guys, you’re making it way too easy for them to win you, and what kind of a prize are you if you’re easy? The answer is the booby prize. Make yourself hard to get. Let them ask you, and you be the one who gets to say yes or no.
2. Don’t have sex right now. I know, I know, it sounds unrealistic and you’re so up for it, but sleeping with multiple guys at your age — or even having any kind of sex with multiple guys at your age — is a bad idea. Casual dating is great. Romance is appropriate. It’s normal for teenagers at 17 and older to be virgins and to be sexually active, but that doesn’t mean it’s right for you. Wait until you find someone you really trust and who trusts you and who you want to be monogamous with, and have a proven track record of monogamy.
3. Get to know all three of these guys a little better by seeing which of them asks you out, and when you do date the ones who ask you out, see who you really trust, respect and connect with.
Good luck!
