There was a great article in Playboy years ago on how to hook up with a girl in a bar. It is the same on these cam websites. Sort of. With a camgirl, we have already established that she is willing to some level of sex work for pay. If you ask these girls in a private tip note they will almost all tell you they have considered taking a Sugar Daddy. They want to be taken care of.
First, or course, you are not going to be successful with most. So keep trying. Second, like a bar, you are going to have to work it. Here are the two main points from that article, modified to website cam girls:
1st. A girl wants you to coax her into bed. Girls want that. Read that article to understand the many reasons why.
2nd. Be a man, talk her on to your dick. Period. Be a man. Do it. And be cool and laid back and polite doing it.
It took me six months of gentle persuasion with my first Chaturbate girl (she is perfect, just like Khaleesi from Game of Thrones)... but as soon as she broke up with her BF she emailed me and I was sitting at lunch with her a couple of days later, and at the hotel for the afternoon within the hour. We still see each other when we can.
You want to present it to them as a Sugar Daddy relationship, and make it worth their while. Before you ever score a date with them, encourage them to sign up on Seeking Arrangment and look in to how much they can make being someone's Sugar Baby. Repetition is the key. And staying cool in the face of rejection
No offense meant to KevinRoby, but that is kind of the blue print to get with a girl in general, minus telling her it will be a sugar daddy, sugar baby relationship.
I mean if you are really looking to hook up with one said girl, sure go for it. But if you don't have time or the means to go through that, just look at the ads here and ask around.
I think most on here, are just looking to hook up. The process proposed by KevinRoby seems like you are approaching a relationship level with the said girl. I could be wrong, maybe there are more guys looking to have "relationship" type experiences in the hobby.
But my assumption as to why most are in the hobby, you want to cut through all the subtext and get to the fun time.
Again, I don't want to start any flame war, just seems like a lot of work for one girl. But if you really want to get with that one girl, maybe it's worth it.
Most of the webcam chat rooms are monitored by the site's moderators. If they notice illegal P4P interaction...the guy will be banned, and the girl is reprimanded and possibly banned from the site. Not many (if any) of the top cam girls, that the original poster is seeking, are willing to risk their cam careers by talking with a bunch of dudes about possibly hooking up.
As always, the hobbyists in the know (like yourself), realize...if you want to rendezvous with a specific top level companion, you contact...Pamela Peaks, TLC, or HelpUBookHer.
For God's sake, it isn't eHarm*ny y'all want...you just want to fuck!
