I feel guilty about my eyes being slightly open during the first kiss?

I am 13 and I got my first kiss yesterday. His eyes were completely shut but mine were slightly open. It's like my whole body went numb and my mind went blank. I tried to shut my eyes but they wouldn't. Does this mean I didn't really enjoy it? I think I did because I can still feel the softness of his lips and his scent and his hands on my cheeks and I got butterflies in my stomach. It felt magical.
