Women should have sex even if they don't feel like it, much as in the old days when a husband's beckoning was all that was needed for a roll in the hay. The argument is simple: back before Women's Lib and a woman's ability to admit she enjoyed sex, women still enjoyed sex during the olden days, even if she didn't initiate it when she was horny. A woman will get into it after the guy starts, the new book says, so she should just give in and let him go for it even if sex isn't the first thing on her mind. Oh, and all the bad sex that results from it? Learning curve, ladies!
