For me, I do like girls with curve. Those model on the walk way are just a disaster for me, their body shape is too skinny. They are so skinny that I won't even erect if they are standing in front of me without any cloth on them. No one is perfect, I believe so. But don't make yourself so skinny that it's more ugly than pretty. I saw this Mayra Suarez nude photo online, I have no idea who is this before I read about it. She was a model, she is kinda hot. She does look attractive but she is very skinny, for me, it's not really my type. Don't get me wrong, it's not about her breast. She have a pair of nice tits, but other parts of her is just skinny. As long as this is the natural her without doing those intense slimming programme, she still consider a healthy person. She do look better if she can slightly increase in weight.
Body curve is important, but not too over. Just have a healthy a balance life you will be more happy and attract the type of guys that love you more than your body. Exercise can help you to have a hot body curve.
