The Dirty Picture star spoke candidly about love and relationships in connection to the launch of a novel called Unhooked which focuses on the relationship experiences of women in urban India, Bollywood Samachar reports.
"There's so much pressure today on girls to have boyfriends," said Balan. "People look at you as if you are diseased if you don't have one. And you are made to feel depressed on special days.
"I have gone through it too. There are no brownie points for knowing your mind and waiting for what you believe you deserve, waiting for your dreams, both personal and professional, to be realised."
The actress said that she believes there is nothing wrong with being single and there is no right time to lose your virginity.
"I was single for a long time and was asked about it. I would say I enjoy being single. Also, maybe because I led a full professional life, I didn't feel the pressure much," she added.
"I have lots of single friends. One of my friends got married at 43 and lost her virginity, that's how she chose it, and while reading Unhooked, I felt as if I were reading her story.
"Also, if you want to have a romp every weekend, that too is fine. One must be free to choose."
Balan will be reading excerpts from author Munmun Ghosh's Unhooked at a launch event in Mumbai.
Writer and journalist Shobha De described the book as "an unblinking view of the contemporary concerns that confront 30-something career women looking for love, but not necessarily sex".
Director Milan Luthria said that Balan needed to become more comfortable in her own skin for The Dirty Picture.
