Men have a cycle they go through similar to the female period (no physical symptoms though) resulting in mood swings. Without living with females it could take place every few months but when a man lives with females it follows their menstrual cycle.

Yeah its called stress. lol

Really ! I never experienced anythin like it , lol

I've heard this before. Not sure I really buy into it though... I mean who doesn't have mood swings over a period of months? And you live with anybody they'll get more frequent... I have my period every morning before my coffee brews.

@RussellB: So your saying you disagree with it. cuz You don't have a monthly thing like women right? cuz yours is everyday thing? Thank god for coffee is all iv got say! lol!

Living with any woman for any period of time is bound to give a man mood swings.

@Ladybug1223: Well not really... I mean my mobile phone acts weird about once a month. Doesn't really prove it has PMS. But based on it's behavior I could argue that it does.

What i know is that men normal circle is 21 days while female normal circle is 28 days, though some female circle is not up to 28 days.

Ripleys beleive it or not?
