i best describe it in a scenario... or a dialogue for that matter..
(the conversation starts with the young couple having unprotected sex)
bf: oohhh...ahhh....yes baby... oh man... im coming....
gf: oh..oh..oh... come baby....come....
bf: aaaaahhhhh.... im home..... omg baby...that was great aint it...
gf: yeah..im tired la... btw, u did use protection rite..?
bf: whaaaat!!! u said u had ur period a couple days back when we were arguing..
gf: nooo...i said that because u wont understand what im feeling at that time... thats why i said that im having a period to make u understand why im upset.. so did u wear or not?
bf: eerr...no
(by this time, the bf's big john 'penis' suddenly shrink to a lovely princess sophie 'dah kecut la for those who tak paham')
7 months later...
the moral of this story is... do your calculations properly.. infact, u could hire me... im doing finance,accounting and management degree, so im kinda good in calculating whatever.. especially when to play and when not to play....hahahah
