IMO the way that most PUAs (MM followers, especially) define and think of attraction is ineffective. They structure their beliefs about attraction in a way that makes it HARDER for them to get laid.
When it comes to attraction, a PUA's focus should be on sexually framing the interaction so that she feels aroused with SEXUAL attraction. All the other things you've heard about attraction - such as like preselection, humor, wealth, and other commonly known DHVs - act mainly as logistical assistance that allows a woman to backwards rationalize her feelings of sexual attraction for a man. They aren't actually part of the main force that pushes the seduction forward.
In my workshops I redefine the classic attraction + comfort = seduction formula into something that looks more similar to the Gunwitch Method
www.gunwitch.com . After chatting with some folks from the mASF forum, I restructured the model of seduction in my head as something more like Sexual Attraction (instead of just "attraction") + Lower ASD (redefined comfort) = Seduction.
I met up with this girl for lunch and sexually framed the interaction with tons of casually sexual remarks, some bordering on GM style of game without the "just kidding" part. I prevented my sexual remarks from making anything awkward by maintaining a strong frame of "this shit is normal." I also threw in some clear SOIs telling her that I think she's a cute girl and stuff like that. I planted the seed for sex location logistics early on by talking about a movie that she just HAS to see and I have it on my laptop. I compliance tested her further by bringing her up to my room to help me pick up some trash. This accomplished two things: 1. It made her invest in me and 2. It primed her to be comfortable with being in my dorm room. We then had to go our separate ways to go to our next class.
The next day we met up for breakfast or a snack or whatever it was and I focused on playing Objection Game (Vin DiCarlo) in order to lower ASD. My main focus was on communicating the message that I'm a very discreet guy who doesn't brag about my "conquests" so I don't ruin any girls' reputations if they do the dirty with me. I did this through a conversation talking about how I like to be discreet out of respect for women. Then we went on our separate ways to go to our next class.
In almost every conversation we had, she wouldn't shut up about her boyfriend who lives miles away in Bumfuck wherever whom she only saw from time to time. He actually called her a couple times when I was hanging out with her and she would answer with "Hey baby" in a sweet tone. I didn't take the fact that she was talking about her boyfriend as an IOD. I just took it as "I don't know what else to fucking talk about" so I just plowed through by flirting sexually and stuff like that. No resistance. Unless she was actually committed to a strict monogamy with her boyfriend, she had no reason to resist flirting with me and stuff.
Later in the day she texted me with "Wanna make out?" I think that counts as an IOI.
I texted back with "Not now, I'm smoking." This acted as push/pull because it isn't clear what I mean by that, or what my intentions are.
Later that night she texted, "You know, I was serious." Or something like that. I texted back, "Oh I know

just close ur eyes and enjoy the ride."
Here's the interesting part: She then asked (over text) if I wanted to hang out the next day and I replied with "K but I can't promise anything besides stimulating conversation," WHICH WAS A MISTAKE. Mixing indirect game like MM stuff with direct game does not fly. She interpreted this as a potential rejection which caused her to attempt to protect her ego. She replied with "You didn't think I actually wanted to make out with you, did you?" I recognized my mistake after a few minutes of reflecting on the dynamics of the interaction here (big advantage of text game) and replied with " "stimulating conversation"

" to which she replied with a tongue face

. That most likely meant that she finally understood that I was just flirting and not trying to reject her.
So then I flat out agreed to meet her up the next day. When she got out of class the next day I just texted her "Come to my room." I got her to come over to watch that movie I talked about earlier. Then, escalation. We did not actually pay attention to the movie.
My roommate walked in on us later and, from the look on his face, I think he saw my balls.
