Now would be the time to take a look at the boy you've just shared a kiss with. If you did a good job, he'll be flushed, heavy-eyed, and smiling.  Smile back at him. He may be nervous about how he kissed, so you'll probably want to convince him that he did a good job. You can do this by smiling. If you arms are still around him, leave them there for a few seconds before taking them away. It might feel weird if you suddenly take your hands away as soon as the kiss is done. Sometimes, the kiss itself is enough of a statement. Sometimes, you'll want to say a little something after the kiss, like:  "You're a good kisser." "I've been wanting to do that for a long time." So, you've finally kissed the boy that you've been dying to kiss for the last six months. What now? You have several options:  Wait for him to make the next move. If you went in for the first kiss, maybe you think it's his turn to initiate the next kiss. Be yourself, do what you normally do, but be friendly and encouraging around him. He should try to kiss you again. Kiss him whenever you want to. Maybe you don't care that much about who kisses whom, as long as there's kissing. That's fine, just make sure that he's into it, too. Kissing him often is likely to lead to a relationship. Break off the kissing. Maybe he wasn't that good of a kisser, or he touched you in the wrong place, or you just get a bad feel from him. That's OK. Try to still be friendly around him, but don't put yourself in situations (i.e. one-on-one, private setting) where he could kiss you again. There are some unspoken rules that you should know about kissing. Pay attention and try to follow them if you can and they make sense to you.  Don't kiss and tell. We know — it's very easy to do. That doesn't mean it's right. What goes on between you and your crush is between you and your crush. Try not to gossip too much about it. Don't kiss when you are sick and likely to spread germs. Kissing is a very intimate thing, but that doesn't mean that your kissing partner wants every single...

TL;DR in Vietnamese:
Khi bạn rời khỏi nụ hôn, hãy mở mắt ra. Hãy nói điều gì tốt về chàng, nếu bạn muốn. Hãy lắng nghe điều trái tim muốn nói. Hãy nhớ những quy ước khi hôn.
