I think that the attitude elduque has comes from stifled feelings about sex. Some things come to mind:

He feels that women hate sex, they just give it to men as a favor for being loving and caring. Once a deep emotional bond is developed a woman can enjoy sex.

To him, sex with a hooker is basically rape, since you are forcing her to have sex with you by providing money, and women hate sex. I think elduque probably idealizes both sex and women as well, and that it may cheapen his own sexual experiences if he feels that even some women would sell themselves willingly.

These are deep feelings, and probably not salient, so that if you asked him, he would deny it, but they still guide his salient feelings on the issues of prostitution.
