To start off, I am an introvert and typically quite reserved. I'm in my early-mid 20s and have been on dating apps for about a year.

I've worked on my looks and pictures, so I am able to get a good amount of matches and have gone on probably 70-80 dates in the past year. I also screen and escalate pretty well so I end up hooking up with roughly half of my dates within the 1st to 2nd date.

"Screen welling" means I list my height on my profile as I am slightly below average height and I only ask girls out that show interest back and those that are okay with mild suggestive flirting. I never double text and I also get straight to the point meaning I typically ask girls out within the first 10 messages. I believe this allows me to screen for girls that are comfortable with the idea of meeting/hooking up and are interested in me just based on physical looks as that is really all they have to go off of give our lack of messaging history.

However, it seems I have trouble retaining/conveying interest as most of these short-term relationships fizzle out or I never make it past the first date with some of the higher quality girls (in terms of looks).

I am of the mindset that guys should not seem needy or be too "simpy" so I typically don't write longer than 1-2 sentences replies, take my time replying (8-12 hours sometimes), and reach out to girls between dates every 2-3 days. I will clarify this is just how I am normally, I’m not really trying to play hard to get. I act this way normally but I justify not needing to put in more effort by believing this to be "dating best practice for men" anyway.

The result of this is that on dates, girls have mentioned that I don't seem to be asking them much questions or seem very interested in them even though to me it seems like to me that I am asking plenty of questions and conveying sufficient interest.

Hence, I am questioning if I should show more interest or work on the quality of my conversational skills? But it is also just part of my personality, as like I mentioned I am more reserved in general. Furthermore, I am busy with my career so I have other things to worry about and don't want to put more effort into dating unnecessarily, but I am willing to do so if that is what it takes to get the results I want. I would like to settle down for a few years to focus on my career so I would rather have a stable girlfriend during this time.

I also think it goes beyond just increasing the frequency of my interactions with the girls or increasing the length of my messages (because I honestly think it is sufficient). Rather, I suspect my messages/interactions lack substance/emotional engagement. Any advice on building an actual emotional connection would be appreciated (or even just general conversation skills).

Another caveat I am considering is that most of the girls I am seeing are in their early 20s, so maybe they are used to guys conveying more interest or "simping"? Compared to the guys love-bombing these girls, I probably don't seem interested at all, or perhaps they think I'm only interested in hooking up (and since they are physically attracted to me they are fine with it but the relationship just fizzles out eventually)

My profile can also come off as pretty shallow (I do have a few shirtless pictures) so maybe I am attracting girls that only want something casual? However, I don't think this is necessarily only a case of me attracting the wrong kind of girl as this has happened with girls that seem interested in something serious initially but things just fizzle out. Maybe I should try some "love-bombing" tactics (but with genuine intent) which I think when delivered through my introverted self, should be a good balance?

tldr; I think I have physical escalation and initial attraction part down, but I need to work on being able to emotionally engage my dates in order to have longer term relationships.
