You don't want to kiss her too hard, too fast, or too sloppily. While your first kiss may make a lasting impression, you also want to find out if you enjoy it as well. Don't rush it. Instead, earn her trust by showing that you want to make her comfortable. Before initiating a kiss, look into her eyes and lean in close. Your intuition should tell you when the right moment is to proceed for a kiss. If you lunge in for a kiss unexpectedly, she may react unkindly and quickly move away. She may also make things awkward with laughter. Giving your date a moment to prepare not only builds the anticipation but also gives her time to compose herself. Is she smiling and blushing or is she bewildered and strained? If she reacts positively continue to flirt or compliment her and express your feelings. If she reacts negatively, just try to naturally move forward with the conversation. Don't ramble or fidget.  If she pulls away, respect her instincts. Give her time to search through her own emotions.  If she smiles, kiss her again!

How would you rephrase that briefly using Vietnamese?
Nhẹ nhàng hôn nàng. Không nên nóng vội. Để ý phản ứng của nàng.
