The campaign, created by Leo Burnett for the website , breaks this week and unashamedly encourages gay men to take the plunge and sign up to the service to find a husband.
One 48-sheet poster asks: "Looking for someone to take you up the aisle?", while another declares "Some guys find a stiff one helps before dating".
Martin Stead, managing director of PinkSpeedDating, said: "What excites us most about this work is that it challenges two category norms.
"First, speed dating has a bit of a stigma attached to it. Second, the advertising industry generally shies away from advertising gay products in mainstream media."
He said that Leo Burnett's work confronts both norms head on.
"The ads romanticise the sophisticated, glamorous and fun PinkSpeedDating experience, while audaciously using humour to target a gay message in mainstream media," Stead said.
The site allows men to register for speed dating events where gay men spend three minutes each with 25 different dates. After the event they can log back on the site and indicate which men they would like to see again, for friendship or more.
If men mutually tick each other they can then get in touch and arrange to meet.
