Atlas,
Have you thought about changing up the pretense you're using to get the girl home? You mention doing the same thing over and over. It seems to me, if what you're doing isn't working, you should try varying things. I agree with the other commenters that you may need to build more connection, and I'm wondering if maybe throwing on a movie is sabotaging that!
I know for me personally, movies are extremely distracting. I cannot hold a conversation with a person while a movie is on; I just end up getting sucked into the movie and can barely tolerate even being talked to because I'll miss the details of the movie. Well, maybe not if it's a movie I've seen a few dozen times, but even then, it's still distracting.
Basically, when two people are watching a movie, those two people are not engaged with each other. They are just two essentially separate people, each separately engaged with the sum of the movie's screenwriter, cinematographer, actors, director and editor. In my opinion it is not generally all that conducive to seduction, although I realize some people do have makeout sessions whilst watching movies. (I have no idea how they do it, I never could.)
The pretense I use to bring girls home is also rather distracting, although at least they're engaged with my own work so it's not quite as bad. But it's still bad, and the first time I brought a girl home on that excuse, I realized it was not helping me. She asked me too many questions about the thing she was seeing and I could not direct the conversation to get her to talk about herself, or even escalate very easily. So the second girl I switched things up.
I still invited the next girl home on the same pretense, but then I just sat her on the couch and started talking to her and we talked for quite some time, getting her to open up, before my even bringing her into the other room to see what she had come for. I have a lot of trouble being physically bold with girls so I didn't escalate nearly enough, but she largely didn't resist what I did do and it's clear to me that I readily could have and probably would've ended up fucking her right there on the couch if only I'd been a little smoother, bolder and more persistent. Before ever showing her what she had come to see.
And as others have pointed out, there's also a time issue. I'd generally have the girl talking an hour or so at the date spot, and then again some more at home.
Another thing that I'm not sold on, although admittedly I still have to perfect my own routine a lot, is kissing a girl before sex is imminent or happening. Some of the most experienced members allude to kissing being potentially counter-productive by releasing the sexual tension too early, whereas you want it to be released through sex! I think in some way we're culturally conditioned into thinking kissing is an essential part of the progression to sex but I'm not convinced it has to be. Now, other experienced guys do sometimes advocate kissing in advance of sex, so it's a bit of an open question and probably depends on many factors, but certainly it's value is debatable so it's at least worth trying sometimes to not kiss and seeing what works better for you, rather than just operating on the assumtion of "I must kiss her".
Some ideas to try out, anyway!
