What Toronto's Finest said.
I've been out clubbing countless times, and not once did I see a girl go home with a stranger. I've cold approached in the hundreds myself, and not one of them would put out. Yes, I got the odd the number or drunken makeout, but those are both a far cry from penetration. Even my very good looking friends were met with lukewarm reactions at best. All this leads me to believe free sex is an urban myth (unless you're into whales).
You want sex? Book an sp. You want to be around a bunch of drunk idiots? Go clubbing / bar hopping.
