It's a big step for sure and it depends on your life situation how big of an effect it can have on your life (parents or family finging out, career, friend circles, online harrassement, etc). On one hand it can be liberating. There is nothing wrong with your lifestyle choice and it's great if you have the courage to do it openly. On the other hand, as with everything, it has it's risks. It's good to be aware that once you do it, there is no going back. Also what you put out on the internet, will always stay there and it will be out of your control.
Most people in the lifestyle don't show their face online and I actually think it can add to the mistery and autenticity, as those who do are often part of the business side of things. Strangers here don't know your circumstances, so only you can decide if this is the right step for you.
