Saying 'I love you' during sex??

Does anyone elses boyfriend tell them they love them during sex? It may sound funny but I came onto my boyfriend last night, gave him a little blow job and asked him to bend me over, after a few minutes he was dirty talking to me and just before he finished he said "I love you" I was just kind of unsure I heard it right I just kept moaning and enjoying the moment until he repeated it again until I said it back. First time he's ever said it during sex and our first month "trying" for our first but 6 months not preventing... maybe his love will bring us some luck🤣 just thought I'd share because I found it weird at first
