Haha, a big thanks to everyone for their comments. 
I just thought of letting the guys here know that women have egos
too, as guys are generally viewed as the ones who have an ego.
Hence, to balance the equation, it's fair to say that SOME women
have egos too.
If any of you thought that i was just bashing the female of our
species, I'm sorry as that wasn't my intention at all. IMO,
everyone has an ego that yields to be fulfilled, just that for some
of us, it isn't apparent.
Eh, I wrote that women have egos too. It's obvious that I'm giving the
indication that men have egos in the first place. Sorry if it
wasn't obvious to you.
Actually, no. I was comfortable with my ex looking at other guys
and she was comfortable with me looking at other women. It's a
matter of intimate trust that we share with one another. It also
depends on the personality of your partner. 
I'm sorry if I offended any women here, and please don't make me
public enemy number 1!
