Really tired of people calling me innocent

A co worker was surprised that I cussed and said she thought I was sweet and innocent. I get that alot though, which I really hate. I am quiet, and keep to myself and I am very friendly but that doesn't mean I am innocent. I am 33 f and I want people to stop labeling me as sweet and innocent because I know it means they think I am naive..and at my age its just weird…like they see me as a child..oddly it's mostly just women that say that to me. Does anybody else get comments like this alot? How do I make it so people stop labeling me as sweet, innocent, etc?
