<human>: Give me a shortened version of the text

This will be our second date. We connected on OkCupid and met up last week for that traditional first coffee date. It went really well... he looked exactly like his photos (this is a good thing), he seemed glad to meet me, and somehow we had enough in common that when I had to excuse myself to go meet my sister for dinner 3 hours later, it still felt like we were cutting the conversation short.

Since then, we've been texting about every other day. The day after the coffee date, he said he had a lot of fun and wanted to see me again, so we set up the aforementioned dinner date. After that, I initiated a conversation, then he started one about an activity I'd mentioned doing.

Anyways, I've been going on a lot of first and second dates recently, but this is the first guy in a while I really am interested in. He's attractive, smart (getting his PhD in biomedical sciences), friendly, and overall a catch. How do I show him I'm interested? I am not particularly good at flirting and I don't want to mess up.
<bot>: Going on a second date with a guy I'm into, and I need flirting tips so I can hopefully secure a third date. Help!
