Is this normal?

Today is Valentine's Day and I went over to my boyfriends, I haven't seen him in a week because we've been so busy so I was so extremely happy to see him! Today he gave me the cutest gifts that were super sentimental and he even fell asleep in my lap while I rubbed his back and brushed through his hair with my hand. In between  the gifts and sleep we got a little frisky and I gave him oral.  While he was asleep it hit me like"wow I really love him and have never loved or cared about anyone as much as I do him" this moment grew on me it became heavier and heavier to the point where when I was sitting on his lap hugging him goodbye he asked me what was wrong and then I said "nothing's wrong it's actually just that everything is right and I love you so much" and then I began to sniffle and actually cried because I'm just so overwhelmed with how in love and how much I care about him. He took it like a champ and his eyes began to water too when he realized I guess they were happy tears. But what I want to know is, is this normal? I've never had this happen before but then again I've never felt the way I feel about him about anyone before.
