How to attract couples and give the right impression?

I'm new to all of this but very keen to get started. I've been reading a lot on here about people saying that ally of singles here are fake and the meet ups don't go ahead. I'm a single 22 year old woman looking to experience a first time with a couple, preferably a little older then I am, and am interested in some bi experimenting. I'm hoping to get some advice on how to attract the right people and show them that I am genuinely interested? I'm not looking for a dinner and drinks, type of thing, would rather meet up and "get down to business" so to speak but I don't want to give the impression that I'm not genuine. I'm also finding there isn't many profiles in my area, being in country NSW.
