Women generally fall into three broad ranges:
Women I'm attracted to but have no shot at. At the very top of this range are celebrities. The bottom would be like a burgeoning model, a legit 10/10 who routinely gets over 1000 likes on Facebook/Instagram for posting badly shot selfies of themselves. Highly successful career women fall into this group as well.
Women I'm attracted to and have a shot at. Top of this range is probably women I have a 5% shot at getting with, bottom being women I could be attracted to under certain circumstances and have a 20% or greater shot at.
Women I will not sleep with under any circumstances. Family members fall in this range, as do women at the extreme ends of the physical size spectrum (midgets, the obese, women who are like 7 feet tall) - basically women that only men with specific fetishes go after.
Here are the types of women that generally believe themselves to be intimidating to men:
Women in the first group. - Generally there is some truth to it as some men will be extremely intimidated by women they perceive to be out of their range. But the real reason is not because of any particular quality, it's because the chances of success are so low it's not worth wasting your time. Ever wonder why famous female celebrities don't have male groupies? Like why didn't Britney Spears (when she was hot) have a group of hot guys trying to get backstage for a chance to sleep with her? Because it's a waste of time and the competition is much stiffer. Instead of wasting your time trying to hook up with Britney Spears, you're more likely to achieve success getting with a woman who's comparably attractive but not rich and famous. Same thing with highly successful career women. If you're an average office worker guy who makes $50K a year, why go after the hot doctor who makes $200K when her cute secretary is right there?
Women at the bottom of group 2 - These are women that COULD be approachable but they do things that are off putting and instead of doing some self reflection, they prefer to put the blame on men for being too scared of them. If you give off negative vibes, people are not going to want to come up to you. It's already low percentage as it when it comes to approaching women.
Women in Group 3 - "I'm curvy and guys just can't handle that" [Translation: I'm 250 pounds and refuse to admit I'm fat.] This is where delusion sets in and women in this category tend to blame men for being too insecure or not man enough to handle them.
