There’s no clear answer to an acceptable age for sex but in India, the legal age is 18 and sex before that can be classified as rape.
The 16-18 period just happens to be an age when both boys and girls undergo a lot of physical transformation which is nature’s way of preparing them for the future.
First-time sex is a special moment. Hence, it should not be rushed into. Do it only when you feel right and are ready for it. Do it with someone you trust and are emotionally connected to.
And the two most important things: do it with mutual consent and don’t forget to use a condom. Stay safe, play safe!
