Is it wired ?

Okay for a little back story when I was younger like age 4-10. I was super shy, but if I spent maybe 4 weeks with someone they would grow on me. But there was a specific group of people who I did not put up with, or some times they would have to try vary vary hard to get me to open up. This Group were men in their 30s or older. If they weren’t my dad, uncles, or family in anyway I instantly hated them for no reason. it’s nothing that happened to me in my past. It was just how it was.
I am 18 now and I can talk people almost any one. but I still have a little bit of anxiety when I have to talk to men around that age. My mom laughs at it but I tell her “hey at lest I am never going to get a sugar daddy“.
