Osho has well said about sex. I dont remember the exact words.. but its somewhat like this... "If you get it, it's like nothing.. but if you don't get it, it will be'the only thing". For example: You brush your teeth everyday.... You brush and forget the whole day about it... but if you don't bursh your teeth, the whole day you will be thingking about it. In other words, it can be said "F**K and FORGET" about F*CK
