Mmmh, I think it says that I prefer...certain kinds of relationships over others. Not necessarily so, but it's what I like most of all.
I always had a liking for strong men. Not only strong in the physical aspect, even if that's a plus.
For my avatar... I think it shows two strong men, strong and confident, even if their roles are quite obvious.
I believe, it displays quite clearly, that a submissive man does not have to be the weaker one in the relationship. Quite the contrary.
And, of course, it displays my fetish for leather.
