Some traditional people may prefer slim women, because they think that kind of body shape looks very nice and sexy, especially when they wear tight clothes. However, not all the people have the same taste, there are some people like BBWs as well. Well, some of you may can't understand it, it doesn't matter! Now, let me analyze some important reasons of this problem to you. Here are them as follow.
The first point is about age. You know that a person always has different interests and hobbies in different life periods. So, we can see that most BBW admirers are those mature men rather than those youngsters. The next point is the change of men's attitude. If you are an adult man and you have some good curvy friends, i believe you can find that plus size people are really nice actually and easy to chat with. So, from this simple example, in some men's minds, BBW is not only a woman with big body shape but also stands for a kind of politeness and good manners. Finally, these men are attracted by BBWs' inner qualities and their attitudes towards BBWs also changed. The third point is revelant to people's former relationship. For instance, if a man had an unhappy dating relationship with a skinny woman, then he may desire to find a BBW next time. That is very normal i think, and it's still a kind of way to comfort himself. Last but not least, as a matter of fact, BBW is not only represents fat woman, there is a little bit difference between BBW hookup and fat woman sometimes. BBWs have good manners and always behave confidently, they seldom worry about that whether men like their big body shapes or not, they just do themselves. So, some mature men who want to find a stable relationship will be attracted by those BBWs easily. That's still an essential point to explain this problem i think.
To summary, in my personal view, young men and adult men may have different choices when they seek for their partners. And those reasons i have mentioned may not overall, but i think you can get some useful information that will do you a favor as well.
