God, I wish you were bi...
Anyway... back to the main point... sounds like you enjoy being in control... and I'm really not all that surprised that guys would masturbate in front of you. Though I'm not sure if how they treat themselves is a 100% accurate indicator of how they would treat you... but it would definitely prove interesting to find out.
Oh and yes... you are very kinky... but in a good way..
"The weakest soul, knowing its own weakness, and believing this truth that strength can only be developed by effort and practice, will, thus believing, at once begin to exert itself, and, adding effort to effort, patience to patience, and strength to strength, will never cease to develop, and will at last grow divinely strong."
