yes, but like milzywilzy said don't do it online. Go to a bar. You have, have, have to talk to women. Its intimidating at first, but so many other guys are nervous too, that just by talking to a girl, buying her a drink and maintaining eye contact, you already blew past 75% of the men in a bar. Once guys start getting drunk (and sloppy) then they approach women, but they never seem genuine. Practice talking to girls before you're sloppy, buy her a drink, look in her eyes, listen and talk. Even if its nsa sex, women need an emotional connection to have sex, they just don't bone at the flip of a coin. Practice, practice, practice! If you can get that far, closing is in my opinion the hardest part. Usually i'll say something like, "want to go someplace quieter where we can talk more?"
if its much more drunk / loud / casual with her, you can just say, "want to get out of here?" if she says yes to either question, she at the least wants to hook up with you, at best bone you. Don't get nervous at that point, just keep thinking to yourself "im in control of this situation, she talked to me all night and is going home with me"
