I am a thin man and I prefer women who don't look like little boys. I don't think skin and bones thin is attractive at all. I prefer a woman between 130-150. Maybe even a little more if she is athletic. Of course there is a point where big is too big but that's also depending on the person looking. Some men really do like very large women and some men are large themselves and prefer someone close to their own weight. I do find slightly larger women the most attractive though. They can still have a thin waist, relatively flat stomach, and weight in all the right places ;)
