This tharki season, the booster of sexual frustration is coming in the form of a feature film. Directed by Akhilesh Jaiswal, film Mastram traces the life of a famous porn writer. For much of the '80s and '90s, Mastram's books were the only sex education most boys in North India got. Mastram then was omnipresent —carefully hidden in secret compartments— but was never properly acknowledged.
