Insights on gemini men?

So i started seeing this Gemini. We hit it off right off the bat, there was definitely chemistry. He is super hot, at first I liked him only because he was just simply very attractive, of course he shares the same humor as mine so that was a plus, but I didn't think much of it, so after a couple drinks and a fun banter, we ended up making out in his car and I invited him up to my place. We fooled around, he didn't bring protection and I having not had sex in a year, didn't care to have condoms just laying around either, so we cuddled and just fell asleep. He texted me the next day, we continued texting and then the day after he asked me when he could see me again. We set up a date for that weekend, and actually spent the entire weekend together (brunch, shooting range....all the fun stuff, and we ended up having sex). He said it was a while since he had such a nice weekend. And I guess this is when I start feeling more towards him, more than just physical attraction. So last night, I drove to see him and we cuddled and watch Netflix, ended up talking with him until 2am about life, the topics we discussed were pretty heavy (especially for two people that just know each other for a bit more than a week), he is a bit more realistic than I am (i'm an optimist and I choose to look at the bright side of every situation). So I felt like that was the first time we discussed something that isn't quite lighthearted.

So I read about gemini and people say to avoid heavy conversations? Is that true? But isn't that a part of getting to know each other more? Everything is going so well now, and I know you might say it's moving too fast but I honestly at this point don't care if it is indeed moving too fast (in the past I have held back and took things slow but that didn't get me anywhere either so now I'm just going with the flow and what feels right). But any insights about gemini and keeping it lighthearted?
