If I may, who are the "wrong people"?
Those two words speak volumes. Alot of people, as you and others have said, have legitimate reasons for being secretive, but why do we need this at all?
Are you really ashamed of people knowing you are involved, in full or in part in the fetish community? I'm not. Good for me, I suppose. I guess its less of a liability for me, right now.
My point in bringing this up however, is that, if you are true to yourself, love yourself, and love others the way you love yourself, then the real you will shine through and anything embarassing won't be such anymore.
I've taken to the sentiment that we shouldn't care what people think so much. We end up shackling and limiting ourselves, our actions, and our possible experiences just because of something silly like this.
While I realize it may not be silly for others, perhaps those that have been in longer than I have, and have truely profound feelings and emotions for the subject, I would imagine that if you can share this aspect of yourselves with us, you could share it with potential dates, friends, etc., online or not.
If they don't accept you, its their own inadequacy to deal with it. Why should you, nay, why should anyone have to lie about this? Its self-punishing, anti-self, and anti-social, in it's own way.
No offense of course. Just a thought, more of a tangent I wanted to share, as an opening was provided in you're two words there. It could be that you meant wrong people as in people that would use the information for ill intent. In which case, I agree with you. I suppose I jumped the gun there, whether I'm right or wrong about you having said that. I also thought though that maybe you meant the latter, which is why I posted.
