How to get an non affectionate girlfriend to warm up to a very affectionate boyfriend?

Anonymous
Title basically explains it.

My Girlfriend isn't the most affectionate person in the world, she's a bit awkward at times and that's just the way she is and she has said this herself. Myself on the other hand am very affectionate and enjoy physical touch etc.

I was just looking to no if this is something that will change in a person?

She's not the most "girly" female but she's not quite tomboy and I do care about her a lot but because she's not that affectionate it gives me the impression she's not as into me as I am into her. Maybe I've just got anxiety of her leaving me Is all.
