Guys, what are the reasons for this?

Reasons why a man would finish early?
So this man I’m dating came round to see me after I hadn’t seen him in a week. He didn’t stay long, he just wanted to see me. I asked him for a quickie, which he agreed to. But then he finished in about a minute.
My question is did he finish early because of the lack of time he had (he was here for about 10 mins) or had he not released in the week previous?

Guys, what are the reasons for this?
