Missing Affection?

Mi
So if you read my post (if you didn't then here's the long story short: over the summer my guy friend and I spent a lot of time over the summer and we kissed ) you'd know that I wasn't sure how I felt about my guy friend. Well after that, I still hung out with him, but we didn't kiss or anything. He's in my psychology class now, and yes we talk and are on good terms, but I miss our summer hanging out. Not just the kissing or his arm around my waist or his hand in mine, but our jokes, and conversations. Thing is, I'm still not sure of how I feel, I know there's always something off when I imagine us being more than friends, but could it be that I'm just scared because no guy I've liked had ever really liked me? Help?!!
