OK Cupid did a study that reported that 100% of women find 80% of men to be "unattractive".

If a man could ask a women over 30 how many partners she's had and get an honest answer (this will never happen) then the answer may well surprise everyone. Double digits would not be at all unusual.
Women do the choosing. There's no getting around that. Stop choosing players and you will stop getting played. It's quite simple.
