Why Youngsters Are Interested In Sex Between 15-18 Years?

I am 20 years boy and I have noticed I mean I just can't understand that in the age of only 15 many of the youngesters of both sexes wants to attempt sexual intercourse. And both the sexes(boys and girls) know each and every thing about sexual intercourse. Why it is happening? I mean Is it a fact or a part of new fashion?

Re...puberty and sexual feelings

Its quite natural to have a bit or more romantic feelings and curosity about reproductive system in teenz as your puberty occurz ,u acquire secondary sexual characterz(pubic hair , enlargement of penis , breast development etc) due to sex hormones ..

 The biology subject in matric (as initially most stdntz had to read it thr was no computr option) creates curosity as we read frog's reproduction cycle

... But these days problem is parents dnt keep a check , islamic teachings are lacking and above all the gossiping friends , media , internet every one creats a rosy dreamy picture to ths aspect so its just aggrevates ..

. N yes as myrizvi said superadded prob is delayed marriages ...

Agreed
