Hey people its michelle here just sharing some advice I have given people that I have met in real life and am passing on to everyone in this community : )

If u arent sure about whether u are GBL
take a step back relax and truely ask yourself how u feel towards them...what guys, females or both make u feel like when u are around them...
some people say wait until u have been in bed with them...from personal experience that doesnt always work that way. If feel the same types of feelings around both guys and girls you are most likely bi..if u feel strong feelings towrds only one depending if u are male around females or guys you are either gay or straight...for females around females or guys depending upon which it is u are either straight or a lesbian...
HOWEVER you can feel strongly mainly for one sex or the other and still be bi. even if u only like one person that is oposite or same sex...

My advice take time and observe the way u feel, act and react around others (your actions and feelings)
then honestly ask yourself again whether u are GBL....
Well hope I helped at least one person with this....If I offended anyone I didnt mean to it is just something that I wanted to share that I find to be true
