The men who said not at all probably don't know just how wrong they are. It isn't necessarily looks or "femininity" with me as much as it is a personality. Some personalities in girls I just cannot refuse them anything.
This will sound kind of like a joke and super arrogant, but I am being very serious. When I was younger I was depressed so I was chubby and not especially well groomed. Nobody ever did anything for me unless they felt like it was absolutely mandatory. Now that I work on my feet all day in a nice restaurant(which means I have to have well above average hygiene) and my favorite hobbies are Tai Chi and writing everybody I know in person thinks I am super convincing.
@Mathgeekjoe - your feelings are extremely common. In my experience working with adult therapy groups, I have met many men (even very large physically powerful men) who are very afraid of women. Perhaps many women don't know this.
