can't get no satisfaction

hey everyone! so i have a boyfriend and i adore him a lot bc he's just great and so sweet. we have just begun dating and i actually had my first kiss with him, which left me weak in the knees but i feel like anytime we kiss after, i don't get "butterflies" or i don't feel that "spark" that people tend to get. i'm not sure if we're lacking something, however, i do seem to get turned on when we start kissing passionately. But is it a bad thing not to feel a spark when kissing my boy?
