Well, I'll add my two cents worth in here! I tried on different avatars, when I first joined, but I went back to the red rose. First off, because of the color, and my nickname, Magenta, the two seemed to just fit.
Secondly, the rose is the flower of passion and love. It whispers passion, just by its presence.
Thirdly, the petals, of the rose, are like the petals of a woman, soft, sensuous, dewy. If you go to the center of the rose, you will find the core, similar to the core of a woman's desire.
So, that's why, I've gone back to the red rose, that was my first avatar, and will remain so, as long as I am a member of this community.
