Dating site Match.com conducted what it calls the most comprehensive survey of singles in America. It looked at relationship trends, shifting gender roles and social taboos.Among single men ages 18 to 70+, the national survey released last December found 95 percent are in favor of a woman initiating the first kiss and also asking for a guy’s phone number. But only 29 percent of women actually initiate the first kiss and 13 percent of women ask for a man’s number.Helen Fisher, a biological anthropologist and chief scientific adviser for Match who worked on the study and analyzed the findings, said the facts are part of a larger trend where women are “piling into the job market, gaining economically, and gaining sexually and socially.”
