I have a friend who is female and very attractive and goes on those sites. She's in her thirties and has been single for a very long time...why? Because she is picky as hell! Guys will need to have a 9.5/10 in looks before she even messages them. If she goes on a date, she'll find something that isn't perfect and then back to the dating pool she goes. In this generation, I think we've become so desensitized to other human beings. Potential love interests are resorted to selfies on a social media site. You can browse through 60 profiles in a minute and judge people without even meeting them in person. It gives the young generation a skewed reality that there's plenty of fish in the sea. The guys will try to find the hottest girls. The hottest girls will try to find the hottest and richest guys. At the end, no ones happy.
To the op, why don't you join "beautiful people.com" if you don't want ugly girls?
