Straight to action is the stuff of fantasy. In the real world it takes a while to find out if a couple is serious about meeting not just you but anyone. Many think they are but in reality they are not. If you actually find one, then the next step might be meeting at a public place. Good luck with that too, because you will find couples all of a sudden no longer replying to you after you've talked about setting a place and time to meet. They may begin ducking and hiding from you online, etc.
There are very few serious and honest people you'll meet here or anywhere online. At parties the personalities there are a mystery too. Basically this is no easy picking but there are those diamonds in the rough. I speak from experience. There are some genuine people on here too, but they are very very few and far between. Nothing you can do about that but be aware of the situation.
