Is that true that men like BBW in many countries On pluscupid.com forums I saw a topic that men in lots of countries love BBWs. Is it true that fullfigured women are so attractive to men?

Of course--the same way some people like shorter people, some people prefer a certain hair color or even a certain ethnicity. Some cultures prefer women (and men) to have certain physical attributes; there are even cultures who find the "supermodel" type of female to be unappealing.

Most people generally have a physical 'type' that they personally find desirable; not everyone wants a thin white person.
