Hello, ibelongtoyou and welcome to this fabulous community.
Here you will find all aspects of life and a truly caring crowd. I believe you will love it as much as myself here.
As for your avatar upon which you wish to see comments. Are your physical fitness great enough to sustain you while being a sub? That one is impossible to answer IMHO. You are certainly fit and will probably be fit enough to do what's required of you for the most, but then again that depends on your Mistress.
As for the composition of your avatar, I find mixed messages. The rope is applied in such a way as to resemble ammo belts, showing a stereotypical masculine credo. Fist over heart are a military style sign showing your devotion, commitment and submission to your superior officer's better judgement.
You sit, quite comfortably, holding your cock as a joystick, displaying to me that you are in control of it. A Mistress will surely be in control of that soon, not yourself.
Don't be discouraged by my writing now. I tend to look at pictures and analyse them for what I see. (Just look up my post in the thread "Your avatar... Why?") Your avatar looks great and if you feel comfortable with it as it is, you should by all means keep it. I just say that how you have chosen to depict yourself is more dominant than submissive. Still, I believe you will catch the eye of a few women as you have good physique.
Now, since I have torn you down on a very slender basis, go out and howl at the moon or hit the sand bags and remember that I am just a nameless, faceless someone who doesn't know when to stop ranting, and I am open for a good discussion. I haven't got many threads, but I do have a few posts. Answer them as you like (within the rules of this forum) and get your revenge on me there.
