Have fun, laugh at your mistakes. Each one will teach you little things that will improve your confidence and your dancing. Don't be afraid to talk to men about the dances and your desire to learn more. In this world of equality between the sexes it's quite normal for women to suggest dancing, although this may be more difficult for a beginner. That's not a serious problem.
Most women are more socially competent than men.
Women don't mind doing one dance with someone with uncoordinated feet, but they rightly object to a man who concentrates his unwelcome attention on one woman. Many men are socially isolated. In dancing they can learn the skills to mix with and enjoy the company of many people. This involves the skills of conversation and a willingness to develop an interest in the welfare of other people. Sometimes men need reminding to keep their efforts public and social.
