My father's friend touched me inappropriately when I was younger

For context I'm F(22). I don't know if this is the right place to post but I just want to share it since I can't with the people around me. As the title says my father's friend touched me in a way he shouldn't have. It was almost a decade ago, I was younger so I couldn't understand much but it just felt weird? He didn't do anything extreme, just pulled me close and kissed on my stomach. That's all, nothing after that incident even though I've seen him afterwards many times. It's been years that he doesn't contact with us anymore and I happen to have grown up. Now these days I've just been wondering what would he have done if he saw me now? I know I shouldn't think this way, it doesn't seem right. But I can't stop wondering what it's like to date someone older than me? I mean not a huge age difference just a few years?I don't wanna think like this I feel like what I think is totally wrong.
