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

I've been talking to this guy I met on okcupid for the last few days. He seems cool- we have some common interests, we're both interested in non-monogamy (he has a serious partner, I'm seeing other people), and from his pictures, he looks pretty cute.

However, he's been texting me a lot- like, multiple times a day, every day. And the texts have gotten extremely flirtatious, even suggestive. I've kind of just been responding, not initiating. I'm not used to frequent texting, especially with people I haven't even met yet. I don't get it, and it makes me a little uncomfortable. Like, you don't even know me yet- where is this interest coming from? I'm not sure whether I'm reading into this because I'm nervous about online dating (I had a bad experience with it in January and deleted my account until two days ago) or whether I should listen to my gut.
<bot>: I'm open to something casual and sexual, but something about the frequency and explicit nature of the texts this guy's sending weirds me out. We haven't even met yet.
