Are the majority of women attracted to nice guys?I can tell you from personal experience that what women say they want and what they actually want are to different things. Every women you will ever meet will tell you they want a "nice guy" but in reality they want just the opposite. As a younger man I was perceived as a "nice" guy and I would watch as girls dated guys who were complete and utter jerks and I would be forced to use the old KY.
The reason is that an attractive women will be literally BOMBARDED with guys hitting on them on a daily basis. Most of the guys will put the women on a pedestal and think that being nice or doing nice things for them will spark her interest but it is the opposite. With that in mind an attractive woman will look for someone who is different, edgy, confident and simply different than the majority of guys hitting on her.
Now that does NOT mean that a guy who is a misogynist sexist jerk will get lots of women. Far from it but it in my opinion it is a delicate balance of being confident, secure and comfortable.
