What are the rules about sex when you’re getting back into dating in your 40s and 50s? Dating expert and founder of LastFirstDate.com Sandy Weiner states that she is about principles, not hard and fast rules. It is absolutely fine not to have sex right away, she states, but urges daters to communicate their attraction so that prospective partners don’t get the wrong idea. As with other aspects of relationships, it is important that people communicate what they want and need. And most important, daters should get tested for STDs and use protection against STDs—this is a very real risk to this age group.
