And therein kinda lies the problem (at least from a guys perspective).
In real life very attractive girls are not approached enough (unless alot of alcohol is involved, even then guys are still kinda eh). The hottest girls i ever dated or were friends with told me they got hit on the most when they went without makeup but if they were looking normal and made up it was rare (Unless it was black guys, they have no shame lol)
On a dating site, theres no risk of rejection for a guy to send an email and also that whole "aura" a beautiful girl has in real life doesn't exist on the net. So basically a bunch of chickenshits fuck it up
that's the dynamics though. nothing you can do..just a social observation
