I think most men who view women as inferior have a problem that has less to do with how they view sex and more to do with respect. Women can develop respect for each other... but it's not nearly as important for them as it is for men. With men, whether it be in the workplace, out with friends, or just a group of guys who really don't know each other... there is an instinct to 'sort out the ranks.' Women have a much, much vaguer sense of this.
Since most women do not understand or partake in this instinctual 'assigning of roles' with men, most men have a tendency to either place women outside of it or some will view women as being inferior to men. This isn't something that men are necessarily aware of, but if you watch them for any length of time... the social dynamics will show you who is the 'main guy' - the one with the most respect... and who is the 'lowest guy' - the one that everybody doesn't respect or even really listen to. All the other guys will proportionally respect/disrespect each other in differing amounts.
If women are viewed outside of this, then men will try to ascertain a woman's value based on what level of respect she has for him and herself. Should he find she has no respect for men or herself... then she is of low value to him. If he continues to find this in more and more women (or believes what he hears from others about it), then he will make the judgment that most women must be of low quality to men... inferior. This is usually how men begin to place women as lower than men.
However, it is possible for a woman to earn respect from a man on this more instinctual level. Self-respect for oneself is usually a quality that most men can understand and appreciate. Willing to give respect to others who have earned it is another quality that men can appreciate too. So during sex, a woman who clearly shows the boundaries of what she will and will not do, and gently explains why will be viewed by a man has having a sense of self-respect in this area of life. A woman who could care less... anything goes, and seems to not care about herself at all... is less likely to be viewed as having a sense of self-respect and will not be appreciated by a man - not really (possibly pitied.. but not respected). A woman who listens to what a man will and will not do during sex is viewed as being respectful toward him... unlike a woman who shows disregard by wanting him to do things he doesn't like. She is also viewed as respectful if she listens to what he likes and doesn't like... and on occasion is thoughtful enough to do some of these things he likes(even if she personally does not like them).
Essentially I think sluttiness and perceived inferiority of the female gender has more to do with respect than simply face-value or misconstrued notions. Even from a chauvinistic pig, respect can be earned by a female.
"The weakest soul, knowing its own weakness, and believing this truth that strength can only be developed by effort and practice, will, thus believing, at once begin to exert itself, and, adding effort to effort, patience to patience, and strength to strength, will never cease to develop, and will at last grow divinely strong."
