Hmmm. What do your friends — anywhere on the sexuality-gender spectrum- think? If your experience resonates with them, we could try and look for an explanation on general. Otherwise, it may be that your selection filters are not truly representative of what you want. 9 months to figure out that somebody is lame seems long, but I agree with you that it is hard to read somebody when you don’t know them.
And don’t go by idiot media myths like “guys want cool girls”, they are based on nothing, just some doofus making an article out of one experience. In any case, why would you want to be what guys want?
