You want a girl who is cool, and probably very attractive, AND cool with having sex with you without actually having any emotional attachment, while you live at home, have no friends, and no car. Lol, good luck. You need to work on yourself, both outward and inward.
Don't go to bars yet. Don't go to clubs yet. Get some friends. Meet their friends. Some of their friends will be girls. One or two might like you. Get a job. Make friends at your job. Buy a car with your money from your job.
Work on your external life: exercise is the most important, which goes hand in hand with good nutrition and sleep: people who are fit and healthy tend to be happier and more attractive as a person. It's not just about big muscles. You'll have more endorphins released, more energy, and more confidence. You can also socialize at or through the gym. Work on your grooming. Are your clothes clean and unwrinkled? Do you smell ok, or at least neutrally (axe and other heavily scented products are a poor choice)? Is your hair/facial hair well groomed, or are you nursing some half-assed long hair and patchy neckbeard? Work on your posture. Stand straight and with confidence. Shake hands with a firm grip, give no ground, but apply no pressure.
Work on your inner life: do you have issues with anxiety, socializing, depression, or anything else which keeps you from an active social life? If so, seek therapy. It's easy to build up an inner story about yourself and the world around you that can hold you back, particularly if you are alone and have no-one to talk to. Take up hobbies. Work on becoming a better person than a better pick up artist.
