Summarize this article:

Talk to the girl about where she feels comfortable going. Choose a location where the girl will likely feel comfortable, such as your home or a hotel room. Make sure you'll be alone and uninterrupted while you're hooking up. For instance, you might take her to your home or you might ask to go back to hers. If you can't take her home, you could rent a hotel room or arrange to go to a friend's home. Consent is essential when you’re hooking up. Don’t assume that she wants to have sex just because she agrees to be alone with you. Pay attention to her words and body language to see if she’s into it. When in doubt, ask her directly if she wants to have sex.  Signs she’s into it include smiling, initiating kissing and physical contact, asking you to do sexual things to her, and getting close to you. Signals she’s not into it include pulling away, looking away from you, and changing the subject. You could just ask, “Do you want to have sex?” or “Do you want to take this to the bedroom?” Hooking up can be super fun, but it’s important to avoid potential complications. Talk to the girl before you become intimate to decide what kind of protection you'll use. Ask her if she is currently on birth control pills, has received a birth control shot, or has an intrauterine device (IUD) to prevent pregnancy. Additionally, wear a condom or dental dam to protect you against sexually transmitted diseases (STDs). Even if the girl is on birth control, it’s typically best to use a barrier form of protection to protect against STDs anyway. Start by kissing her on the hand, arm, or cheek. Then, give her a passionate kiss on the lips. If you’re both into it, kiss her in other intimate places, like her neck, breasts, or thighs.  Go slow at first. Give her a light kiss and gauge her reaction. Don’t use tongue when you first start kissing her. Build up to it so she doesn’t feel like you’re rushing things. She’s going to be more interested in a hookup if she feels sexually excited. Don’t rush things by trying to start intercourse too soon. Instead, take your time to caress her, kiss her body, and rub against her. This will help her get into the mood for sex. For instance, start by gently caressing her body. Then, move from kissing her lips to making a trail of kisses down her neck, chest, stomach, and thighs. Simply shift her clothing or remove it as you go. Don't just get up an leave after a hook-up. Instead, talk to the girl to make sure she enjoyed it. Then, clean yourself up and get dressed. If you're at her place, thank her for having you over before you leave. If you're at your place, offer to help her get home safely. If you've gotten a hotel room, ask her if she'd prefer to stay overnight or go home. Both your and her experience will be better if you part on good terms. Show her that you care about her health and well-being by helping her get home. Offer to drive her home or to call her a ride if she can't drive herself home. If she's got her car and feels comfortable driving herself home, walk her to her car and ask her to text when she gets home. If you stay the night together, talk to her before you fall asleep so you both understand each other's expectations for the morning after. For instance, decide if you're both okay with the person who slept over leaving without waking the other. While you might not be interested in a relationship, it's still important to be kind to the girl you hooked-up with. Tell her that you enjoyed meeting her and had a good time. Additionally, ask her if she had a nice time so she feels like you care about her.  You might text, "It was great meeting you last night! I had a great time and hope you did, as well." You don't have to have a long conversation with her. However, sending a check-up text shows her that you don't just see her as an object.

Summary:
Take the girl somewhere safe and private so you can be intimate. Check in with her to make sure she’s consenting to sexual activity. Use protection to prevent pregnancy and STDs. Kiss her to initiate physical intimacy. Engage in foreplay to help her get turned on. Be considerate of the girl after you've hooked-up. Make sure that the girl gets home safely after your hook-up. Text her the next day to check on her.
