<human>: He (26) saw me on an adult site (for finding friends with benefits) about 6 months ago. He said he was captivated by me and was persistent with messaging me, but not too much that it was annoying. It was quite sweet. I was interested but we both didn't have privacy (our own place to fool around) at the time so we didn't meet. 

Then a few weeks ago he asked me out. I tried to clarify with him. He was adamant that he really wanted to date me. I can tell he's very attracted to me. 

Our first date went well and we kissed a ton at the end. Then I set up a few more dates. We got a bit further sexually, but we haven't had sex yet. 

I haven't ever really dated properly before... In the past I was always clingy and jumped into bed too soon. The guys did too. 

This time it's different. He said he was ok with me seeing other people and that he might as well. Though we did say that if it got serious we would become exclusive to each other. 

This is my problem: I feel like when I'm with him he's smitten with me, but when I'm not he doesn't contact me very often and when we text/chat it's like he's multi tasking and replying to my texts with short replies after several minutes.

Tonight I said, "it's ok if you're busy. We can chat another time." Then he actually had a real conversation with me...but I seem to be carrying the conversation for the most part. 

Do some guys just suck at coming up with things to say? Or should this be really effortless?

Any insight would be awesome. Thank you.

<bot>: Dating a guy that seems really into me, but seems like he could care less when we text/chat online. In the past, I've been clingy so this time I'm trying really hard not to be.
