What are some things most people of the opposite sex do that you find unattractive, but since everyone does it you have to deal with?

For me, as a guy, this would be having a girlfriend that dresses revealingly. I prefer to have a relationship where seeing me shirtless or seeing her cleavage is exclusive to her and me. It feels more special and intimate for me to see parts of her that are otherwise not able to be seen for me and especially for others.
