Girls, What do I do about this guy I like?

I met him about four times before. He is a friend of a friend. He is tall, built and good looking with a rugged beard and a deep voice. All of us went to the mall and I wore my jeans and crop top. A group picture was taken and he put his arm around me and tickled my waist. He asked me if he could walk and talk with me and I said yes. He bought me something to drink and we chatted and flirted a bit and we exchanged numbers. When it was time to go, he offered me a ride home and I accepted, when he dropped me off and walked me home he gave me a kiss on the cheek and lightly touched my belly. Should I call him first or wait for him to call me?
