Why do things just limited to a body need ?

In the past driven cultures of indian family we are so confined that we do not want to connect with our own part of life that leads to human production, i want to drive your attention towards the problem of teen girls which they face bravely but many of them got tired of their own creation, this seems odd to listen but
Yes for this me and you are resposible who could not connect our sisters,our girl who should be given proper take care while their period of menstruation instead of passing lame jokes which we do but it became intolerating when it comes to our own sister why is it so ?
This is just because of development of the knowledge which lacks sensitivity to the emotions and understanding of these aspects.
You know if we could help our sisters classmates and other girls with this proper care instead of the dominating sexual desires of our own then we can stop this and save first our own sister
And then thousands of them who just get fed up because of this and let the destruction of their own.
When girls dont get the proper attention from their family brother and friends then they get involve with stranger who just overwhelmed with joy which seems them as a perfect one but dormanted by the greed of their own which that girl cant understand and which also somehow seperate the girl from his family and this is how things go wrong for her and when her family tries to make her understand then her intellect is not enough mature to understand that.
Coming to my question which is an answer to all those who just have a illusionary thought process of so called love and end with so called completion of sexual desire. This seems odd talking like this me being a 18 year old guy can tell you that from my schooling to starting of college life met with no of peoples and what was common thing in the perpective of most of them to be in love had been the reason of their sexual desires which one way or the other being dominant on them and somehow they fooled themselves and let this term give the name of love. If you are thinking that my words are castles in air then gentleman pay attention to your own family and see what was your own reaction when you find someone from your family was in a relationship your sister or someone else the first thought which strikes your mind is that this all could lead her to gateway of vanished career and You always try your best to stop her .
But my friend when you me and others do these things we thought that our intellect is enough mature to take decisions then why do we do that when it comes to our sisters ?
then you know a thought always strikes in our mind that in this age group our harmonal and all neurosystem and understanding skill works that way that these desires get dominant on us even you will be suprised to know that india is one of the country which has millions of youth involved themselves in watching the porns at their early age which fulfills their mind not with the constructive part of sexual reproduction but with the one that will harm themselves their relatives one way or the other. Why this problem being mobilised in this country with a very fast pace and the answer lies in the way we our family and friends take this not as a constructive part of life but as a sin or a destructive part which we find will only lead to the destruction. If we want this system of illusionary diversions to not dominate our society then mr . Reader you need to be the one who should start from himself to understand everything and being the one who supports his sister in every aspect and help her in the best possible way and let them understand with everything on their own but along with knowledge which could embrace their knowledge in best possible way to achieve their best in their lives.
