Childhood memory grossing me out

So when I was younger my stepdad used to stick his tongue in my ear (not in a sexual way) to try to tickle me. I didn’t know any better but looking back it makes my skin crawl with how uncomfortable it makes me ughhh. I have no relationship with him because he abused me and my siblings.

The reason it’s been bothering me recently is because I was making out with a guy and he started doing that and I was just like 😖😖😖 bit I didn’t say anything. I just don’t like that lol.
