Tough question..
1) Both are together purely for physical intimacy? No strings
attached.
2) If there's love, sex is not the main thing ba. I dun think a man
would leave a woman juz bcos she's not willing to do it if he
really loves her.
3) Perhaps many people perceive this as a 'healthy relationship'.
Some people believe that love and sex comes as a package. But I
think sex only comes into the picture if both are really sure that
they love and trust each other.
I know u will correct me de.
Actually I suddenly ask this question because I watched the 9pm
show on channel 8 last night..
chen shu chen had an affair with a woman even tho he's married. The
woman really love him, and did not ask for much in return, juz
hoping that he will visit her maybe once a year. But after sex, he
heartlessly said that they have made a mistake, and knowing that
it's a mistake, they should not continue. Then he said sorry he
cannot commit to her. And he really left her behind.
I think he's selfish and irresponsible. The woman trusted and love
him. But he left just like that. Well it's true that he cannot
commit to her because he's married. But since he knows he cannot
commit to her, why start? And when things has reached that stage,
then he said that it's a mistake? Did he love her?
20, 30 years later they met again. And he told her that they are
good friends. She even bore him a son. Just good friends?
sorry i think im getting a bit carried away.
Maturity as in?
What I mean here is before marriage, rejection and not
incapability.
I know what you mean.
I know man perceive sex differently as woman.
That's why the question... coz I dun understand what a man really
thinks.
Simi lah...
How you know I would reject leh?
I think there's nothing wrong in asking a question ba?
So would you please enlighten me?
