<human>: Can you give me the gist of the text in a nutshell?

I haven't done much dating in my day, I was kind of a late bloomer.  I dated my first serious girlfriend for a few years, and after I broke up I went through a time where I didn't date anyone for almost a year.

I've been dating recently, and I've realized how hard it is to meet a random person you click with.  I'm not expecting anything out of it, but I'd like a relationship again, and I figure that if I'm not going out on dates then it's stupid for me to just wait for it to "just happen."

The problem is that I get set up on a lot of dates with people that I'm just not really that into.  It's not that they're bad people, they're fine, and fun happy intelligent individuals, but (at least in the case of blind dates) I get set up with a lot of people that I don't find a lot of physical chemistry with.  Then we text back and forth for a short while, set up a date, I meet them, and almost immediately I'm not interested in them (most of the time it's a physical thing).  I know it's bad to reject someone just based on their looks, so I'm always open and careful to get to know them before writing them off based off of how they look.

That being said, much of the time I don't feel a lot of chemistry with someone, and I'm not really sure how to proceed.  I find myself in a situation where I now have tons of dates and this happens a fair amount (then again, there are also people I *am* attracted to and go out with for a while, but ultimately we haven't been compatible for deeper reasons like religion, places in our lives, etc...).  How do you reject someone lightly without making them feel like shit?  I feel honestly bad, because these people have taken time out of their busy schedules to go on a date with me, and I feel like I'm wasting their time.
<bot>: I want to know what to tell people when I'm not interested in them or not feeling it because we have no chemistry, and I want to do so without being a complete jerk.
