I suspect that you are a lot more likely to get outed if you use other internet social media. The entire purpose of sites like Facebook is to track your personal info and sell it. If you want to be safe, it is a good idea to use a completely separate user account on your personal computer to keep male and female activities separate.
Personally, I am only discrete for my wife's sake, otherwise I would put up a picture of my female self at work. I look forward to a day when there is no fear of being out. Honestly, compared to wrestling and other mindless male activities, what is there to feel bad about??
