Caitlyn Jenner has revealed her isolation from the transgender community and says she has "a lot of catching up to do".

The former Olympian - who was known as Bruce Jennder before her transition - has opened up about her journey in the first of a series of articles called "The Real Me" which will explore people and issues in the LGBT community.

Jenner wrote in an article published on WhoSay today (June 6): "Up until now, I have totally isolated myself from the transgender community so I have a lot of catching up to do. I feel such a responsibility to this courageous group to try to get it right and tell all sides of the story. To me, that's always the biggest question: am I doing it right?

"A few weeks ago I had dinner with some of my new friends - a group of six trans women - and I went around the table and asked each of them how long it had been since their transitions. One said 20 years, the other one said 15 years ago...seven years ago...three years ago… They came around to me and I said, 'Two weeks.'

"Flash forward a few weeks and I’ve already learned so much about this community, the issues, and the people involved. It’s been an eye-opening experience for me - mainly realizing how fortunate I am."

The star added of her new group of friends: "Seeing how my new friends have overcome their adversities is such an inspiration. They are so well-adjusted and smart. I’ll be sharing their stories here in the coming weeks and I can’t wait for you to get to know them."
