How can you be pro-abortion, anti-prostitution?

If you feel that a woman should have the right to choose in the case of abortion, the choice being that she kills the live being that is human inside of her, yes it is a live human being and can be identified as such easily and scientifically, why should she not have the right to choose weather or not to take my five bucks for something else that she will most likely regret/ could cause her physical harm? I see hypocrisy in the lurch!
