Its a little hard to understand why we maintain a female breast titty taboo in this day and age. Before the internet, curious boys had to find back issues of National Geographic or find someones collection of porn to see the endless variations of the female breast anatomy.
But now anyone with a computer, can spend 24/7/365 doing the same, and its in a video format, one can watch those female breasts react to the dynamic stresses of the entire range of suspended free weights in motion.
But still, such human nudity taboos persists unabated. By world standards us Americans are more sexually uptight than average, but it really has to be over the top to demand females be covered head to toe in burkas in public.
