'Sensitivity' is an overused word; one may do better by calling the ideal male 'sweet' and 'kind' or 'nice.' One thing to note, however, is that women, while they are ultimately the ones who decide with whom they are in a relationship, only decide among what may be considered applicants.
This is where one enters into a conflict. Women want 'sweet' and 'kind' men; however, these men are generally too 'sweet' and 'kind' to actually pursue a comparable girlfriend, because said girlfriend will be simultaneously worried about 'not being good enough' or 'being a bitch' to the 'sweet' and 'kind' male -- and so they manage to dissuade the considerate male, who doesn't want to press the issue with an uncertain girl for fear of being forceful or insensitive.
This is, coincidentally, why assholes or bold males tend to get girls; they are routinely more forceful in pursuing their interests, and so girls are convinced to date them despite that they would prefer other types of males.
"Bobby, I'd like to -- but I'm really not sure I could give you the sort of attention you deserve. I'd hate to come across as a bitch..."
"Jenny, I wouldn't mind at all; any time would be cherished, but if you think otherwise...."
"Bobby, I'm really not sure. You've got sort of a bad reputation.."
"Don't worry about it, Jenny; y'know how those rumors go. Just try one date. You'll love it."
