Smooching someone you trust can ease a lot of the anxiety of your first kiss.  If you knew you were giving someone his or her first kiss you'd try to be patient and understanding, so expect the same of your partner.  Keep in mind that an awkward first kiss isn't the end of the relationship (or the world).  Actually, it can build intimacy through having a shared experience.  As long as you can laugh it off, you'll be fine. Remember, everyone has gone through having their first kiss.  Odds are that most people are more awkward about it than you'll be, even if you don't know it. .  Use chapstick or lipgloss to smooth over chapped lips, and brush your teeth and tongue well.  If your mouth feels a little stale, use breath mints or spray to freshen up.  Knowing that your mouth is clean and appealing can help you feel more confident about kissing. That being said, though, don't feel like you need to obsess over cleanliness.  Most mouths just "taste" warm, unless you've recently eaten something pungent (like onions or garlic) or you've just woken up in the morning. You only get one first kiss! Unless you’re both so overwhelmed with desire that you have to kiss right now or the world will end, draw it out. It can be tremendously exciting and sensual to tease the kiss before it happens, keeping eye contact the whole time. If you're nervous about not knowing the right techniques, let your partner initiate what happens during the kiss.  Imitate what he or she does until you're comfortable trying your own moves. .  As you become more comfortable with kissing, try to take the lead on initiating kisses or working on new techniques.  If your partner doesn't respond well, simply write it off as personal preference and try something else.

TL;DR in Indonesian:
Cobalah memilih pasangan yang bisa dipercaya. Siapkan mulut Anda. Jangan terburu-buru. Biarkan dia mengambil inisiatif lebih dahulu (tidak wajib). Mencoba mengambil risiko yang telah diperkirakan.
