Justin Bieber is FTM. It used to be my headcanon but now I believe that all of that is true. He looks like a totally different person than what he was 4 years ago. That is a short amount of time to change so fast. My theory is that he was born female and he was intersex so his mom had to make the decision to keep him as female or male. As he got older and was a kid he presented as male and he got hormone blockers at a young age so his breasts wouldn’t grow. He wasn’t on testosterone yet once he made it big on youtube and once his fame started to grow. That’s why his voice was high pitched and he could sing really well. Then of course was the hate that came with the fame. I think that he got tired of everyone calling him gay and a girl so he wanted to start on testosterone fast. Not to mention he looked 12 when he was 15 and he hated looking so young. And he wanted testosterone to feel more comfortable in his body. I think in the future he might get phalloplasty so if you ever see Justin’s arm all bandaged up then you know that what I said could be right.
