Does this mean the sex was good for him?

I had sex with this guy for the first time the other night, and he didn’t even last a full minute. It was probably like 30 seconds. Does that mean he liked it? Also, I did suck his dick for a little bit before that. I’m kind of self conscious about how he felt about it because he didn’t say too much. He did say he wanted to do it again another night, but I don’t know if he meant it or if he was just saying it to be nice.
