Doctors tell media outlets that Petras has been going through hormone therapy since age 12.
Petras says she is happy with the results of the operation, saying "I've been asked if I feel like a woman now, but the truth is I have always felt like a woman. I just ended up in the wrong body."
In addition, Petra shares "I can enjoy swimming now and wear bikinis, go into changing rooms without a problem. Everything has changed because of this operation. I just can't wait to put on my favorite bathing suit and go swimming like I've never done before."
What do you think about a 16-year-old having a sex change? Is it too young?
