as opposed to ending up with a girlfriend.

Prior to discovering the community, girls naturally became girlfriends once we were attracted to each other. We'd go to the beach, watch a movie, go for a meal, go for a bike ride etc. (boyfriend girlfriend things) and somewhere along the way we would become just that.

Now that I am getting better game I have several girls attracted to me, and but don't want any as girlfriends (as that would stifle my progress), but of course need to escalate from # closes to sex. I am pretty unfamiliar with this process, its not my natural mode of behaviour.

How can I make sure she knows she isn't entering into a formal relationship?

How can I maximize my chances of success even if she were hoping for a more formal relationship?

My current guess is disqualifying her while escalating and building attraction/tension. Something like bait-hook-reel-release: "I don't date girls that X."

Is it better to be direct: "I'm not looking for a girlfriend" while building attraction and tension?
