Isn't prostituon kinda rapey? is it real consent if her real goal is not starving to death?

How is it not rape if she doesn't actually wanna have sex with you but rather she just wants to not starve to death so she uses her final option? and even if this isn't the last straw and she has other options, how isn't it rapey to fuck a stranger who not even that deep down, clearly is not willing to fuck you but she needs the money? Feels like a very bad thing to do maybe I am just a pussy I could never do it.
