It's not about prostitution...it's about trying to define a relationship. Is this only a sexual thing or is this more? "You ask what is this/Mind your business" is her attempting to get more, and him refusing. Tricky is defining the relationship as purely sexual ("Is this love/No not love/She turns my sexual tricks"), but Martina is trying to push for more. At the same time, Martina is questioning her actions, "Will you spend your life with me/And stifle me."
