It's not possible to put a curb on pre-marital sex and the best way to curb AIDS is to play it safe, preached tennis sensation Sania Mirza [Images].

In the city to take part in the Hindustan Times Leadership Summit, Sania skirted questions that had anything to do with tennis but spoke about other issues.

''Look, whether it's before or after marriage, people should have safe sex. And about pre-marriage sex, you can't stop people and hence the best way is to play it safe,'' said the teenager, who shared the dais with Miss Universe Natalie Glebova and formula one driver Narain Karthikeyan [Images].

Karthikeyan, meanwhile, threw his weight behind South Indian actress Khushboo, whose remarks on pre-marital sex has snowballed into a major controversy.

''I think Khushboo stressed on safe sex, even if it is pre-marital, and it spiralled into a controversy partly because of the media,'' Karthikeyan observed.
