.  If it's done right, a kiss can be the most effective way of turning a girl on. Keep your breath fresh with some gum or mouthwash and keep your lips loose. Tight, puckered lips is how you kiss your grandma! You should also keep the tongue action delicate (at first). The motions should be light, soft and alternate between fast and slow. Know where to put your hands.  The back of her neck, the sides of her face, or around her waist are all good areas for your hands to rest during a kiss. If you touch a girl in certain areas without her consent, it is sexual assault.  A simple "Is this OK?" is enough.  If she says yes, you're all clear; if she says no, stop immediately. Many girls are way more sexual than you, potentially. Give them credit for that and there's nothing wrong with telling them how much you want them (once you've gotten your foot in the door a bit). This actually turns them on! Think about it: you feel turned on when you feel desirable too. Don't be really gross about it but don't be afraid to tell them how sexy you think they are and how you can't wait to get them in bed. If you tried some of the suggestions above and she seemed receptive, here are some more intimate areas you can work with, using light touches and soft, slow kisses.  Neck, throat, collarbones and shoulders Feet and ankles The small of her back (toward the bottom of the spine) Back of the knees Inner thighs Ears The inside of her upper arm If you find an area where she likes to be touched, don't overuse it. Instead, back away from it for a while and slowly make your way back, touching everything around and up to it.  The anticipation will make it more intense when you finally do touch her. Leaving before the other person gets bored is a good rule for most social interactions, but it's particularly important here. If you break off contact while she's still interested, you'll be on her mind constantly.

TL;DR in Vietnamese:
