2 more number closes today. mixed feelings

so today, I did a bunch of approaches, and only got two number closes out of it. I'm kinda happy, but I really wish I did better.

First approach was a HB6(nice tits) working on her laptop. I approached her with a functional opener by asking her what laptop she was using, and asking if she would recommend the laptop, for I'm trying to get a new one. She responded politely, but when I moved on to tease her, she just wasn't feeling it. She looked really occupied by her laptop, so I ejected.
Second set was another HB6(with revealing clothes) sitting by herself. I used another functional opener, asking her where the financial aid office was. She responded politey, so I moved on to some banter. I teased her for giving boring handshakes, then ran the handshakes routine on her. She was enjoying the conversation, we were having fun. I kept teasing her, and she was eating it up. That was until she had to leave, for her ride was waiting for her. So I let her go.
Third approach was a two set, HB5(fat) and HB7(cute but skinny). I took a book, and asked them if they thought a certain guy in the book was a guy or a girl. I later added some banter, switched to comfort, included a little bit of kino, then moved in for the number close by inviting them to a party of mine. They hesitated about the party, so I told them we should hangout anyway, and still took their numbers regardless. I think I did a decent job with this set, but it just didn't feel authentic enough. I feel like these numbers are flakes.
fourth approach was an HB6(nice skin). I ran a situational opener, asking her where she got her salad. Then I teased her for not liking subway, moved into some comfort, and realized she loved clubbing, and loved hip hop music. We spoke about our favorite rappers for a while, then I moved on to some qualifying questions by asking her if she was adventurous. She seemed to be investing, so I moved in for the number close, but she said," I can't do that because I'm married". I personally don't want to mess with married people, so I resect that. So I spoke to her for some more time, then ejected. No number code, but it was fun talking to her.
Last approach of the day was HB7(russian milf). I ran a functional opener by asking her where the W building was. After noticing her accent, I asked her where she was from, and we went on from there. I moved into comfort this time before adding some banter later on. I teased her for making her hair looking fake, and also teased her for being a nursing major. We were having fun. Then all of a sudden, she she had to leave, for her ride was waiting for her. At this point, I'm starting to get annoyed at being cut short because they have to go home.
I had the opportunity to approach many more sets, but I just felt crippled by my limiting beliefs. (Sad)

With all this being said, I've realized the following,

I need to implement more kino into my approaches, but I just don't feel comfortable doing it during day game. I need to find ways to do it comfortably and authentically.

I need to improve on my general game in order to avoid flake outs. I'm not doing anything terribly wrong right now, but I just need to improve on my authenticity.

I need to improve the speed of my game in order to quickly game people before their rides cut me short.

Questions:
I've also been interested in landing a kiss close during day game, but I don't know how to go about it. I know I need to up on the kino bit by bit, but it just isn't the same during day game. How can I go about doing this? Also, how do I go about upping the kino in an acceptable way?
Lastly, I've heard many PUAs talk about being sexual without talking about sex. I've searched the internet for ways to be sexual, but no avail. How do I achieve a sexual frame without talking abut sex?
YOUR HELP IS GREATLY APPRECIATED
