Sex burns calories: 54 min of sex burns a whole pizza pie

Today I have a funny story to tell you. Yesterday I was reading in an italian newspaper an article about italian nutrition expert Bruna Fabbri. She found out that 26 minutes of sex with orgasm burns around 300 calories -that is 1/2 of pizza pie. So if you eat a whole pizza pie, you will have to have 52 min. of sex to burn it off. Now I know why some of my friends who eat pizza are so skinny :)
