Only with openness, can awareness start. We live in dangerous times. I think parents should be more open about talking to their teenage kids about stuff like why should one use protection, how it helps. Why shouldnt one share needles etc etc. Unfortunately most parents, especially in India, tend to get to so cagey and uptight about the whole issue, they alienate their kids.
Mistakes happen because the children have nobody to turn to.
They can't go to their parents because they fear shouts and sometimes even beatings. I read somewhere that safe sex is more than carrying a condom like a credit card. Safe sex is feeling safe with the person you are having sex with. I guess what's where I would start if I were to spread AIDS awareness in my community.
