@lostalone:
The whole point about coming out is opening ourselves to let others inside a previously hidden part of us.
By that definition, we also invite rejection and avoidance.
As long as you're not harming others (by having a double life, say), the only metric you should use is how comfortable and free you are with your life decisions.
If you find yourself enjoying a more subdued life without being out and proud, then by all means, you do you.
At the same time, I find myself questioning the idea that being out in any way = being shoved in a certain box and treated accordingly. I don't think you're giving your friends enough credit.
By you coming out you can prove to the people around you that you shouldn't be "shoved in a certain box" the more people come out the more we can break those stereotypes. I am certainly not a stereotypical gay man and I have even had people say that I wasn't what they expected.
Just be you.
