Sounds like your dates are just boring and don't build any sexual tension?
What do you usually do with them? What setting, what do you do, for how long?

I'm giving the following advice because you said "usually by then I tried multiple different approaches to close." Since none of them have worked, I'm assuming that your methods of closing are uncalibrated and need work, so I would start there.

If you want to avoid girls saying they're goin to leave, then you need to escalate better. Girls could literally say "I can't wait to suck you off as soon as I get to your place" over text and then do absolutely nothing when the time comes if you don't escalate it. Think of common activities that girls will agree to do but will give you an excuse to sit close to them (watching netflix on the couch, eating a meal at the table, sharing a drink, etc.) This gives you a socially acceptable reason to get physically closer to the girl, and then you can build sexual tension from there.

If the date went bad it’s usually unlikely of getting a second date. That’s why when going for the close you have to be almost 100% she’ll be receptive. Examine her body language, build sexual tension with good eye contact and maybe some sexual innuendos here and there. How she reacts to physical touch. One time I was with a girl and I went for the kiss and she pulled back. So I just went back to vibing and building more comfort. More light touches and before I knew it I had my arm around her rubbing my fingers up and down her shoulders. Then I began kissing her neck and things escalated from there

Yeah. You handle it by not letting the vibe down. Take a look at the video title "How to vibe/flirt with a girl" on my YT
