Questioning Question

Hello, everyone. I hope you are well. I didn't know who else to ask this question, and I figured this was my best bet.

I have thought I've been straight for...I guess my whole life. Dating guys, however, has been weird for me. I am uncomfortable with shows of affection, I've felt nothing when given a kiss. I think I can acknowledge when a guy is good looking, and I think what really appeals to me is personality, but any thoughts of any physical intimacy with them scares me. I wanted to know if this felt familiar to you guys. I don't know if I don't like guys, or if I am just asexual or something. Can I have your thoughts, please?

Thank you.
