Should I kiss a guy on the Cheek?

I've been dating this guy for 3 months. Within the 3 months we've seen each other 5/6 times so 1-2 times a month. When we went on our 4th date he asked if he could kiss me and I immediately laughed because I was cut off guard that he asked and because the thought of a guy wanting to show me affection makes me feel uncomfortable. We've talked about attachment styles and he knows I'm hesitant to show affection because of my childhood trauma. He's been really patient and understanding with me but I could tell I hurt his feelings when I rejected his ask to kiss me. I would love to be more affectionate with him but it makes my skin crawl when someone tries to show their affection for me. Part of me thinks I'm unworthy of love maybe? Sooo should I kiss him on the cheek next time I see him? Would he appreciate it? Or is it weird to kiss a guy on the cheek? Thxxxx
