He said the L word during sex?!

My boyfriend and I have been seeing each other for a year, but only in an official relationship for two months. There are reasons behind why we took so long to officially date that I won’t get into, but it wasn’t anything negative. Yesterday while we were starting to have sex for the third time that day he asks me “did you hear me earlier?” and I hadn’t so I asked him what he said, and he said “I said the L word.” and I asked him when and he said he said it while he was cumming the second time. I wondered for a second if it meant anything because I know a lot of people mistakenly said it during sex without actually meaning it. I asked him if he meant it and he said yes, and I said it back. I meant it. He said it again multiple times that night. Do you think he meant it? Or was it just a prolonged heat of the moment thing?
