Pakistan is an Islamic Republic with the highest porn-watching population in the world. That statement in and of itself signifies a particular aspect about Pakistani culture: we are horny and desperate for sex, but God forbid we actually engage in it. Sex in Pakistan is considered a taboo topic. Men generally aren't judged for it in our patriarchal society but if a woman from a middle-class family or underprivileged background is caught having premarital sex, serious shit goes down.
Women from poorer backgrounds could be victims of various forms of premarital punishment. Punishing women for premarital sex started with former President Zia-ul-Haq's dictatorship or "Islamization," which incorporated Zina (stoning to death), and Hudood (punishments such as whipping, amputation, honor killing) into Pakistani law. His government dismissed women's rape accusations, instead labelling them as fornicators and sending them to jail. These draconian forms of punishment are slowly dying out, but still linger in the mentalities of fundamentalists, imams, and police officers. Shariah Law can also be blamed for many gender discriminatory policies in Muslim societies, such as the lack of support for freedom of speech, women's rights, and, ultimately, human rights.
