Did I say something wrong?

i went on a date hiking with a guy in the mountain. We were walking and talking. But then I saw that he got out of breath and looked a little like he was really tired on the verge of collapse. I asked him " are you ok? do you want me to carry you?" Then after that, his body language and vibes changed and it looked like he began disliking me. Towards the end of the date, he asked "why did you ask to carry me?". I replied: "because i felt really bad... you looked like you were about to collapse". He said "I was just gasping for air because we were going into higher altitude (harder to breathe). I just felt so bad for what I've said. He was a scrawny guy. I think emasculated him by asking to carry him. It hurt his self esteem. He might not have taken it so offensively if he were a bigger guy
