Why do people like any part on the male or female body? (Breast, pectorals, legs, feet, gluteal muscles, penises, vaginas,) Adults are usually attracted to specific parts of the human body because of the events that occurred during their childhood and adolescent years. I have a preference for women with large natural breast, and it is probably because of an event that occurred when I was 11 years old. It was the first time that I watched an X rated movie. The movie featured a woman named Christy Canyon and she had large natural breast. It was also the first time that I masturbated.
