I agree with bubblegum_kiss, you should be sure that it's worth thw possible consequences. Things happens and secrets get out. I personally would not reccomend it, but you are old enough to make your own choices. Good luck. :)
As long as your prepared for what's going to happen with you, if one of the guys is dating somebody else then your going to really have it from one of those girls.
I wouldn't do it because it would come with a bad rep when it got out...even if you are single honestly (I'm just stating the facts) hooking up with two guys in one night makes you look like a HUGE slut.
Nothing is ever ok or not ok in my eyes. It's all about what you as an individual person thinks is best for you and the people you are associated with.
People will always have one night stands, have group-sex with friends or associates and to be honest i see nothing wrong with that. It's your life, you may do with it as you please.
All i can say is be sure of the consequences and stay safe. Even if you don't want people to know what you're up to, let at least one person know where you will be in case something happens and you go missing. Always protect yourself sexually, not only with condoms to protect you from STD's but also with some birth-control, be it pill, injection, implant whatever.
It's up to you what you choose to do in your life, i'm not going to judge you, but as long as you know the risks and take precautions to minimise them, i see no problem in it.
