Duh.
But at least science now proves it.
Scientists demonstrate that for men with "hostile sexism" (e.g., men who think women have vicious motives in their relations with men) the area of the brain that processes objects lights up (rather than more interpersonal areas) when they see scantily-clad women.
This idea of sex being distorted as an objectivization of the woman is a theme in John Paul II's excellent book Love and Responsibility. He distinguishes in marital love between seeking the spouse using pleasure as an object and seeking pleasure using the spouse as an object. In other words, if your goal is sexual pleasure, and you see your spouse as a means to that pleasure, this is a distorted and damaging view of the marriage relationship and will adversely affect it. If, on the other hand, you're seeking to love your spouse as a person, even giving yourself to him or her, and you see pleasure is a happy accident, your relationship is much more healthy.
