i don't mind at all i'm 21 but i'm too chicken to do it though and what if i made a mistake?
what mistake can you make?
look, you're on JUB, so i'm guessing you KNOW that you must be at very least bi. i'm guessing you've accepted that much internally, and especially if you're wanting to come out. that's half the battle, and for me, that was 90% of the battle.
so here's the thing, you're 'chicken,' and you don't want to make a mistake, and what not. that's fine though. so you're afraid. so? i was afraid, i was f-u-c-k-i-n-g petrified of telling someone, anyone that knew me personally. you know, the very first person i told, i told face to face, and it was my oldest friend, (i decided i wanted to do it face to face) so i had texted him and told him i needed to talk to him about something serious. anyways we met up at his place, and i just came over and started talking to him. i pretty much just told him that i had something to tell him, and after telling him like 3 times how nervous i was, i just said it.
you can still do this even if you're 'chicken,' and i know you can because i was the exact same way. so here's what you do, you start thinking about a setting where you want to tell whoever it is you want to tell. maybe you want to be alone with someone and tell them, ok, so where are you one on one with this person? maybe you want to tell your parents together, (if they're still together) ok, so where/when can the three of you sit down and talk? visualize where you want to tell them, and then make sure you get into that situation, and then say that you need to talk to them about something. that's what i did.
yes, it's scary, but you can do it, even if you're petrified of doing it. anyways, when i got back from my friends house, the first guy i told, i was literally shaking afterwards. i shook for like 20 minutes, i dunno if it was adrenaline, or whatever, but yeah, i was definitely scared.
so what mistake could you possibly make? do you think you're gay or bi? if you think you're bi, dude, there is no mistake lol. you're on jub, you definitely love dick.

and if you are bi, it wont matter if you later go after a girl, or whatever. if you come out as bi, and it turns out you're gay, you can slowly get more comfortable with the notion of being fully gay, and slowly start identifying yourself more often around others as gay, if asked.
i say make a plan in your mind how, where, and when you want to do it, and then make sure you're in that situation you want to be in where you can tell someone. anyways, that's my advice, i hope you are able to come out soon enough.
