Many men like to have multiple sex partners. Its in their genes.
Just go to geylang to take a look at the crowded streeets, you will
know what I mean.
If you are not the type who can accept a man who always like to
have sex with new girls, then just spare yourself the pain, and let
him enjoy himself.
Such men will never change, as it is in their genes. Remember, it
is not your fault, so don't feel hurt.
