Returning to dating—especially online dating—can be a daunting prospect for men in their 40s and 50s. Dating expert and founder of LastFirstDate.com Sandy Weiner discusses some of men’s biggest fears about online dating. Their main concern, she says, is that the women they date will be frigid and that there will either be no sex or it won’t be enjoyable. Men’s other concern is money—some men worry that women are interested in them only because of their money…while others are afraid that women will reject them because they don’t have enough money. To avoid these fears, Ms. Weiner suggests that daters have an open and honest conversation with new prospective partners.
