Taking into account all the issues alreday mentioned I think a factor that is sometimes overlooked is physical attributes. Small mouth and big cock must create more discomfort and more reluctance. Also I think it depends on what a guy expects from a blowjob. Everyone knows how unpleasant it can be to have something at at the back of you throat and what the 'gag reflex' is like so it you're happy to have the top couple of inches sucked I think even the most reluctant woman would find that pleasurable. It's probably the fear of having that hand on the back of their head that puts a lot of women off.
