Some men like to prey on women and take advantage of their emotions. For instance they see a plus size woman that may not have as much confidence as her slim friends and feel she is ready for the taking because she is desperate. Such delusional thoughts is what makes relationships fail before they even begin.
Yes. When guys feel that a certain type of woman is easy they are thinking incorrectly and getting in over their heads at times. If more guys would actually look at the real woman instead of the window dressing they will find some great women come in all sorts of shapes and sizes.
I have met more easy skinny women then heavy ones. Might just be that they are more in tune with their own self-worth due to abuse when younger buy mean children. So if you see your self as valuable your not just going to throw it out there for any pig to gobble up.
