You need to have a statistically significant sample. I would say somewhere in the several thousands and it should be a sample with diversity, meaning many different cultures, ages, ethnic groups etc ...
What's the common factor in your experiences? You. The logical conclusion would be that the women aren't the problem, you are.
It's called anecdotal evidence. It's not the same as peer-reviewed, double-blind and repeatable evidence. Your isolated experience does not mean the same thing happens for everyone, everytime. Personal experience can be used to illustrate a point, but it's not evidence in itself.
Again, if you are as smart as you think you are, this should not need to be explained to you. It's logic 101.
