Have you ever considered that
your experience is the exception?
Most women don't approach males. Go to any pub or club and you'll see that there's a difference. Men dont get ready for a night out and then sit around waiting for women to approach them. It just doesnt happen like that.
No - I'm saying a girl just has to look average or above, but for a man that isn't enough.
There have been multiple scientific studies to back up that the market is in the woman's favour.
E.g.:
"For instance, in response to the sex request, men indicated an average likelihood of 46, a whopping figure compared with women's average rating of just 4. "

"In every case, men preferred significantly larger numbers of sex partners than women"
"Men were more likely than women to consent to sex after knowing a potential partner for time periods ranging from 1 hour to 2 years"
"A diverse range of research findings lead converging support to the notion that men have a specialized psychology that leads them to consent to sex more quickly than women"

"Gender differences are strikingly large for incidences of masturbation and for attitudes about sex in a casual, uncommitted relationship."
