This is why museums are so wonderful: walking around, observing mankind's joyride from slime to WiFi, you see incredible ironwork, inspirational pottery, fabulous vellums, and exquisite paintings, and - across these disciplines- tons of fruity historical humping. Men fucking men, men fucking women, men going down on women, women pleasuring themselves - it's all there. Every conceivable manifestation of human sexuality, in clay and stone and ocher and gold.
