<human>: Hello!

Throwaway because the guy in question is on reddit.

Anyways, I had created an online dating profile a long time ago but was never really active on there. I decided to meet up with this guy who seemed cool and was pretty keen to go on a date with me. 

Anyways, it's been about a month, and we've hung out about a half a dozen times (and FWIW, yes, I've slept with him). He seems to be more into me than I am him. He's cool and stuff, but I just don't get butterflies like I did with my ex. I'm also not used to all of the attention he is giving me (texting me throughout the day; wanting to plan trips for the spring, even though we're not even in a relationship). I told him we needed to slow things down and even though it's been more than a year since I've broken up with my ex, I guess I am still not over him. I am gauging everyone against him and no one is measuring up. Specifically, my ex's charisma and goofiness. This is one thing that I realized I really liked about my ex. The new guy seems too serious for me.

This isn't fair to the new guy. But I don't know if this is how dating works?? My ex was my only real relationship; I never "dated." Are you supposed to feel the chemistry right away or is it something you grow into?

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Late bloomer on the dating scene, still not over my ex. Wondering if chemistry is felt immediately or it needs time to build?
