I'll thank you not to speak for me as to what i want. And i'm sure i'm not the only one that feels this way. The reality is the perception of beauty changes culturally. Your claim that all men want a slender woman reveals your ignorance of history and the impact of culture on perceptions of attractiveness. History has proven that the modern concept of sexy and beautiful is the opposite of what the past thought. It used to be that heavy women were the preferred body type. Look at the old paintings, and statues. The female images were almost exclusively heavier women, because that was what was viewed as sexy and beautiful. The women men lust after now were considered to look sickly and frail and not attractive. The assumption was that heavier women were healthier.
So the reality is men tend to gravitate towards what they perceive as healthy according to the culture. And even then it comes down to each persons personal preferences. Really, what you're talking about is lust, not what someone wants in a long term mate.
In the future keep YOUR opinions as YOURS and don't push your crap off on everyone else to keep your butt out of the fire. If your lust after someone to marry, thats on you, not every man.
