Article in English: Let them know you want to make the experience as enjoyable as possible. You don't have to get awkward and directly ask, “What ways do you like having sex?” Instead, express that you care about their likes, dislikes, and boundaries in an appealing, relaxed way. While it's helpful to talk about likes and dislikes ahead of time, talking about turn-ons can also be really sexy in the moment. Say something like, “So where's your favorite spot to be kissed?” or “Tell me about something you've always wanted to try in bed.” Asking someone what they enjoy sexually or what they fantasize about puts them in a vulnerable position. Let them know that they can trust you and that you won't laugh at them or judge them.  Confiding something about yourself first can help them feel more at ease with you. Try telling them how you like to be touched or a position that you enjoy. Talking about preferences in advance can make sex more enjoyable, but you don't need to go overboard and make each other uncomfortable. You and the person you're into don't have to share your deepest, darkest fantasies, especially if you don't know each other very well. It's one thing to say that you like having your ear nibbled on or neck kissed. However, don't go into too much detail about your experiences or talk about past lovers as if they were conquests.  No one wants to hear all about the last person their date slept with, and bragging about sex is a major mood killer. You can say "I like kisses on my neck," but don't say "Man, it really turned me on when my last girlfriend kissed my neck and gave me hickies." You don't want to make turn-offs the main topic of your conversation. However, the experience will be more fun and less awkward if you know that a spot is extra sensitive or a position is uncomfortable for your partner. While it's good to check in now and then, asking, “Are you alright?” every 30 seconds is a turn-off. Be attentive to their body language, and try to stay in the moment instead of overthinking things.

Summary in Vietnamese:
Hãy nói đùa về những gì làm họ vui để bắt đầu buổi nói chuyện. Cho họ biết bạn sẽ không phán xét. Nói về những điều bạn thích nhưng đừng ba hoa về hành vi lạm dụng tình dục của mình. Hỏi về những gì họ không thích.
