My idea of beauty in other women is focused on the face, especially the eyes. Windows to the soul, and all that. I like women with kind eyes.
After that, the overall shape means more to me than any one part.
For myself, I wish I had more in the boob department. I always had a cute bum, even as a guy, and HRT hasn't done it any harm. And I am happy with what HRT has done for my eyes.
