Boss behaviour

I work for a company that like to blabber on about good work practices and slogans yet really there is not much evidence of any of it in practice. My main grip is my boss, who I think is inappropriate but nobody else seems fussed. He acts up in front of women being an employee or customer - Example- Staring at them up and down, comments on their attributes, talks about having sex with them, says inappropriate things in conversation with them, if in his opinion a female is not up to his level of approval he will comment, talks about cheating a lot, the list is endless yet I'm the only one who seems uncomfortable with this attitude and when I try and steer a conversation away from this happening I am talked to as if something is up with me! like being called gay... is this normal in the work place as I have little experience with this being my first job. what can I do if every route seems to condone it.
