“One day my colleague, David Buss and I were chatting and I said to him, "Nobody's ever looked at why people have sex," says Cindy Meston, psychologist at UTexas Austin and author of the book, 'Why Women Have Sex.' She and Buss rectified that. 1,549 undergraduates settled on 237 reasons for sex. Women listed as their top 10 reasons, (1) I was attracted to the person, (2) I wanted to experience the physical pleasure, (3) It feels good, (4) I wanted to show my affection for the person, (5) I wanted to express my love for the person, (6) I was sexually aroused and wanted the release, (7) It's fun, (8) I was horny, (9) I realized I was in love, and (10) I was in the heat of the moment. Men had the same top three, with numbers 2 and 3 switched. Lower in the top 10, men mix in - I wanted to achieve orgasm, and, I wanted to please my partner.” MenSexWomenStudyPsychologyCase Study Book:Brain Trust: 93 Top Scientists Reveal Lab-Tested Secrets to Surfing, Dating, Dieting, Gambling, Growing Man-Eating Plants, and More!
