My personal opinion is that there is nothing great about what you've chosen to do.
Personally I don't believe in gaming within any social circle. If you game anyone close to anyone you regularly hang out with, you're putting your reputation within that social circle on the line. I'm still speaking from personal experience, but your reputation within a social circle is a kind of foundation you use... like hmm... a stove where you build a fire. You don't cut up the stove and start burning it... unless you're REALLY desperate, and then what happens - you wreck a good stove and have to get another one.
I coin that analogy because I use my carefully built reputation within my social circles as a tool to DHV to a girl I bring into my life. I'll invite her to one of our social gatherings, and she can see how much fun I have and how people like me. Then if it doesn't work out, you can move on and bring another girl in. And your reputation as a ladies man keeps increasing, and within the social circle, guys look up to you, and girls want to get to know you better.
What you're doing is really bad IMO. You're creating a reputation as a guy that hits on every girl he can and has no luck. People will be reluctant to introduce you to their female friends, they don't want you to scare them away.
And this will cripple you internally too. I can tell by your post it's negatively effecting you, because you can see it all happening and you know everyone knows. This lowers your self confidence and probably gives you less reason for yourself to go and meet random girls instead. Sure meet girls at parties but don't leap frog from girl to girl that happens to be put in front of you, geez.
Also my opinion on you not developing real feelings for girls is tied into this somehow, whether it's a cause or a symptom. Just like feeling crap at sex the first time and not really 'feeling' anything, with practice you get better at feeling things.
I urge you to get "Man Transformation" by David DeAngelo, and listen to disc 10, 20 times in a row!! Specifically the speech by David Wygant. He's all about how girls are looking for special moments, not pickup lines. If you go out, see a girl doing something, make a comment on it, be happy and positive (don't snap her out of her reality with some random "pick up line" question), you attract girls by being real, present, and positive. The routines you are trying are not working, and never will.
And untill that, he's all over YouTube. I suggest taking time to go inside yourself, watch this stuff, study it, think about how you can apply it yourself, and take the time to re-learn things, before you set out trying PUA again. It looks like you're at the same stage where I had to do the same thing.
