Its not White Pony and I don't think its some sex show in Amsterdam either. I've been to Amsterdam and seen sex shows, they happen indoors on a theater stage and usually are pretty gimmicky, like a couple fucking with techno music while doing gymnastic sex, or people dressed up in costumes fucking, stuff like that. There really aren't street side sex shows, the only thing sexual out on the street are the tons of whores standing behind glass doors who try to get your money, that and hype men standing outside venues to try to get you to come in and watch a sex show.
