Yes, some will judge, but some wont, its best to give subtle hints at first to gauge the persons reaction. Ways to drop hints are like if (this recently happened to me sorry if it sounds too specific) someone is talking to you about a recent school dance or something similar where you may be asked to slow dance with someone, when talking about it drop a hint or two, like if they ask if you danced with anyone and you say no, just say something like you'd probably not like to face with someone of the opposite gender (this was over text and I responded like 'fr dancing with a guy is grossss', I'm lesbian/ bi if your wondering, still figuring it out). This is a nice example, and another less specific one is wearing something subtle, like a bracelet with the flag colors, if your comfortable with it of course, and a less obvious one is wearing a thumb ring, and if your lesbian you can try the carabiner Clip code, you don't have to do the top and bottom thing, it can just signal that your lesbian, and if your a guy you can do the hanky code, which is kind of the same thing but with a handkerchief, you can look it up, but for bisexuals you can do either, there's also nail flagging, and you can pain one nail differently, you might have to look it up for more info, but after all of this, if they haven't asked and show that they are ok with this stuff, then tell them! And if they've shown signs of disliking the things you are doing because 'its gay' then they might not be the best person to tell... I hope this helps and gives you ways to tell others while still feeling safe! Have a wonderful next 24 hours!!!
