I Need To Change My Way Of Thinking

Hello, first post! Although it's going to be a rather distressing one. I have been having issues lately with feeling uncomfortable around my dad. I'm 23/non-binary, and although my dad tells inappropriate jokes at times, he has always been there for me and I know that he doesn't harbor weird feelings for me. However, I can't seem to convince myself of that and stop feeling uncomfortable around him. He has never done anything inappropriate to me, however, when I was growing up, he'd sometimes make comments pointing out my body features (mostly my breasts, but my mother did this as well). I have pointed this out to him and the comments stopped, but I still feel uncomfortable around him at times. I have OCD so once I have a thought, I think about it constantly, especially if it's distressing. Gotta love mental illness, I tell ya. Any thoughts or suggestions are appreciated.
