Normally 桃花运 means that you meet someone by chance and luckily you two become lovers. If you are single now and your friends might say this to you :"希望你今年走桃花运啊“ And that means hope you can find someone you like soon.

其实真正知道“桃花运”是怎么回事的人并不多，许多人甚至认为那是好运，其实根本不是地么回事。 这是一个命理学术语，讲起来非常的复杂，它真正的名称叫作“桃花”、“桃花劫”或“桃花煞”，总的来说是个灾星。按照四柱命理学，人有生辰八字，这八个字会形成60*60*60*60，一千多成种组合。而在这些组合中，每个看天干地支，遇到了另一个天干地支，就叫做见“桃花”，如果是八个字中，就有，那叫“命带桃花”或“命里桃花”，如果八字中没有，而是流年中出现，那就是“桃花运”，也就是在运程中出现的“桃花”，多为因为男女之事而遭遇不好的事，所以，是个“劫”而不是什么好运。 “桃花”主男女之事，主风流，主才艺，主美貌。如果是命带桃花的人，多聪明有才艺，男人风流好色，女人貌美不守妇德。但也要看人制无制，也就是还会分成“墙里桃花”和“墙外桃花”，如果是“墙内桃花”为有制，多为优点，貌美、有才艺且不风流。如果是“墙外桃花”，就是个下贱的命，尤其是女人，人人得而可妻之。 大凡演员、艺人都是命带桃花的人，所以，今天他爱她，明天她爱他，一点都不奇怪，他们得到美丽的外表与才艺的同时，也天生风流。 如果命里没有桃花，只是在流年中遇到，那过了流年一切变成泡影，最后落得到人财两空，声名狼籍，所以千万不要觉得遇到了“桃花运”是件好事，那是一劫，“桃花劫”，小心了。

For example, if you are a boy, and you meet a girl, and the girl likes you, or you meet some girls, and the girls like you, I would say, 你交桃花运了。恭喜你！

桃花运 in Chinese actually means "luck in romantic relationship", its not just sextually.
