Was India More Open About Sex in Ancient Times?

I was watching some videos about India's history, and I came across something really interesting... It seems like people in ancient India were much more open about sex than they are today. So I decided to look deeper into this and found that... There’s plenty of historical evidence that suggests that ancient india was more progressive about sex and sexuality than the india we know today—homosexual themes in literature, erotic carvings on temples like Khajuraho and Konark, and, of course, the Kamasutra. Even texts like the Manusmriti and Arthashastra acknowledge different sexual orientations and practices. I also remember hearing that the Mahabharata and Ramayana mention aspects of homosexuality, though I can’t recall the exact details. It feels like sex wasn’t such a taboo back then, it was just a natural part of life. But over time, maybe because of colonial influence, people's views have shifted. Now it feels like having sex is seen as a crime; you can't be open about your sexuality, can't let anyone find out that you have sex, and I feel like girls are punished more for this than boys. What changed? Why is it that now having sex is seen as something shameful?
