Back when I was a schmoe, I always loved off-season female bodybuilders. Something about those curves...
Even then, I was cool with non-fbbs who were 'thick', meaning big, but still firm...not fluffy.
These women are often (not always) good in bed and almost always have high sex drives, because they are built for baby-making and want to be pregnant all the time.
They make good mates, because they tend to be loyal and are very protective of their young. Also, they have a lower rate of failed pregnancies than skinny chicks.
I will not, however, fuck a fat chick. Never have, never will.
