Being outspoken

On the social networking site facebook, I posted a dialogue fromasap a movie 'Mandira punnagai'. The dialogue goes that you are not ashamed to shout out booze but feel shy to ask for a condom.
  No one commented nor said anything about it on site. I didn't much care about until Ma'am had asked about my posts there on facebook. I started to ponder about it, why is it such bad.
  Then the next day my senior in NCC asked if I had any problem regarding a picture I posted which states 'no gf no prob'. Then he asked why I posted xxx messages (as quoted) I merely stated that it was only a dialogue and then thought what was told in the post was only done.
  We are shy to talk about condoms while it is a matter of utmost importance. I feel satisfied that I had talked about publicly and done justice to the post.
