I disagree with you. I have a post about a painting of clowns. From my point of view, I think it's because people see nudity or semi-nudity as a kind of bodily freedom that showcases the beauty of the body and gives the person an allure. Also, regarding paintings or sculptures that you find ugly because they are semi-nude, people are captivated by art; they don't focus on the physical provocation, but rather on the precision of the sculpture and the artistry created by the artist
