Well, many passable TS on myspace or facebook, never
say they are so, so nobody knows. Those that do post
and are out and proud are often the least passable, often
because they don't want to fit the binary.
So, if you say your TS and look good they don't have
much to compare with.
I'm on facebook and I get guys stating that I look like
a goddess and want to be my undying "friend" once
a week

. Not sure they'd say that if they knew I was TS...
