How to talk to this guy..?

Well, hes friends with my friends but ive never really talked to him until last night. I went over to my friend drews house and he was there. We ended up talking and eventually, kissing. He gave me his number and when i left, we texted that night until we went to bed. Then the next morning he texted me but we didnt really know what to talk about..now im scared to text him because i dont want him to think im boring! Im sorta intimidated by him, too. :/ What can i do/ say to get him interested in me??
