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