Male fruit flies feel pleasure when they ejaculate

New Scientist 

Male fruit flies seem to enjoy ejaculation as much as men do. Their "orgasms" seem to be satisfying enough to reduce their craving for other rewards such as alcohol. The experiment resembles the "orgasmatron", a fictional machine for giving people instant orgasms featured in the 1973 film Sleeper. Galit Shohat-Ophir of Bar-Ilan University in Ramat Gan, Israel and her colleagues engineered male fruit flies so that they could make them ejaculate at will. First, they genetically engineered neurons in the fruit flies' abdomens so that they could be activated by exposure to red light.
