What's sexy about someone has a lot less to do with their shape and more to do with their eyes and smile and a fearlessness about being themselves. I tend to be attracted to people who are a little bit different, who don't fall into the typical run of the mill "pretty" category (that includes ultra-thin). I tend to like curvy or athletic women and men who are cuddly.
Everything will be ok in the end. If it's not ok it's not the end.
