Well, to sound.......polite, we can change the meaning of "Voluptuous" all we want, but there is nothing voluptuous about anyone who is morbidly obese. And there is nothing attractive about it, either. Also nothing attractive about a much-shorter lifespan. And there is a huge difference between someone who is 20, 30, or even 50 lbs. overweight (like the guy in the blue shirt, pictured above) & someone who is over 100 - 200 lbs overweight (like the woman pictured above).
I wanted to be clear on the meaning of "Voluptuous," (since it's so often used) so I looked it up.
What does voluptuous girl mean?
A voluptuous woman has a soft, curved, sexually attractive body: a voluptuous body/mouth/figure.
