1. It's true that some men prefer a slightly fuller woman, and this is related to certain cultural notions of beauty and reproductive instincts. However, this represents a minority of men's preferences, not the whole population.
2. More men are actually more attracted to women as a whole, and body type is just one of many factors, not a dichotomy of "chubby" or "slim". The key lies in the health and tiness, as well as features, temperament, character attraction.
3. Everyone has different aesthetic standards, influenced by culture, upbringing, and personal experience. So it is impossible to give a unified "all men like XX type" such a conclusion. Any such absolute statement is not rigorous.
4. Love and attraction go far beyond body type. Most men and women consider a wide range of factors when choosing a partner, and appearance is only a small part of the equation. As they interact, their inner character, intelligence, and attitude towards life become more important.
5. Some women also prefer slightly bigger men, but again, this is a personal preference and not relevant to all women. Love is never about size.
So, in general, this "all men like XX type of women" is too absolute and one-sided to be valid, culturally, psychologically or biologically. Any healthy relationship should not prioritize body type, and attraction between people is made up of many complex factors, of which body type plays a minimal role.
