Under the racy slogan "the first time is just for love", Vladimir Putin supporters have posted a series of videos aimed at young voters in an increasingly intense Internet election campaign battle.

And the answer is clear: "Putin -- the first time is just for love."

"You know doctor -- I am very scared, although my choice is one of love," one of the videos shows a girl, played by an actress, telling her doctor.

"Of course I understand. Everyone is afraid the first time," the doctor replies.

"The main thing is to trust your choice. Because trust is love. And your choice you can trust," as the camera closes in on a picture of Putin amid romantic music.

The girl is then shown happily walking to the polling station.

In a second video, a doctor tells another girl: "The main thing is to be sure it's safe. Especially the first time."

But as the camera again finds a picture of Putin, he says: "With him, it will be safe." Again the video concludes with the girl casting her vote.

Advertising agency Aldus ADV said it made the videos (www.perviiraz.ru) with the aim of "attracting a young audience to take part" in the March 4 presidential elections that Putin is widely expected to win.

The agency did not say who commissioned the ads. It is not clear if Putin's campaign is directly linked to the videos, but his team has never been shy of using sex as a weapon to attract young voters.

Ahead of the December 4 parliamentary polls, his party United Russia issued a video which showed two young people meeting in a polling station, apparently making love in a polling booth and their casting their votes together.

"Let's do it together," said the slogan, leaving little to the imagination.

The raunchy videos come in a campaign where the Internet is playing a role unseen in previous Russian presidential elections, with all sides trying to outdo each other for supremacy on the net.

Putin's team enlisted A-list Russian celebrities to take part in a campaign called "Why I am voting for Putin" but this was shadowed by allegations that some stars felt obliged to participate because of their state-funded projects.
