I find its a far more a difference between "everything is about me" type personalities, and "it's probably not about me type personalities" than anything to do with gender. What I mean by this is the difference between people who think you drank the last coke to annoy them and people who think you drank the last coke because you were thirsty. I've found it with both men and women, one man I held a door open thought I was treating him specially because he was in a wheel chair. I hold doors open because it's a nice thing to do and avoids people getting doors slammed in their face, it's just good manners, if people want to think I'm doing it because I think that they are unable to it's quite fine by me. I think you're over thinking it but it's good to be cognizant of other people's feelings, you'll go far further in life by catering to those who appreciate having doors held open and asking about weekends than you will by catering to the misanthropes who see ulterior motives in everything.
