Flirting lets a guy know you’re interested in him without being too obvious. Engage in some light banter--tease him (but not cruelly). You could even tease him about the fact that he hasn’t kissed you (which should be a major hint to him that you want to be kissed.)   Flirt with him over text. Flirtatious, funny texts can be a great way to 1) let a guy know you’re funny, 2) show him that you’re interested, and 3) keep him thinking about you even when you are not together. Just be sure not to overload him with texts--that can feel overwhelming and be a bit of a turn off. Make your guy feel like he is the only guy in the world--and the strongest, sexiest guy at that. Giving him a confidence boost may give him just enough confidence to get up the nerve to kiss you! Ask him to help you lift something or open something for you. When he has done whatever it is, say something ‘ooo look at those muscles.’ Even if you just say something complimentary like ‘I love your eyes,’ you are sure to stroke his confidence. Sometimes you just need to be direct. If you have given as many hints as you think you can drop without acting like a crazy person, its time to just ask for a kiss. Just keep in mind that being direct has its pros and cons. On one hand, you will get your answer (and hopefully your kiss) immediately--on the other hand, that answer may be ‘no.’ If he is a really shy guy, he may need to just work up to kissing you on his own. Another possibility is that he is not as into it as you thought he was--if that’s the case, don’t lose heart. There are plenty of other fish in the kissing sea. You can make your question sound sexy while still making it clear that you want to be kissed like..right now. When you are close to him (such as when you are pretending there is something on his cheek--see Part One) lean in close to his ear so that your lips brush it gently and whisper “kiss me” or something along those lines. It is more than likely that that little brush of your lips and your bold request will drive away any...

TL;DR in Chinese:
跟他调情。 让他觉得自信。 让他亲你。
