Omega/AntiHeather is sexier and better looking than everyone on here put together, but that doesn't mean that all the other girls are ugly.
Wolfgurl, hale_bopp, and Shima are all pretty hot, some in slightly different ways than others. PI also strikes me as being very sexy, even though I do not know what she looks like.
BTW just because I say that I think a person is sexy does not mean that I like them or even get on with them. It is just my honest opinion of their physical/sexual attractiveness.
