chemistry and kissing

i had a crush on this guy and he had a crush on me. we started hanging out a lot. we’ve been growing closer and getting kind of attached. i was attracted to him a lot. he doesn’t have a lot of experience with anything so i’d say we’ve been moving slow. we’ve kissed twice and they were short nervous kisses. i didn’t feel much. does this mean we won’t have physical chemistry or is it not enough to tell? i thought i was really attracted to him but now i just don’t know
